Need help with setting up multiplayer for 10 ish people per server room + login etc.

[PaleoTheUndead]

Like the title says, i need help with multiplayer. I want to make a top down 2d zombie survival game in a mmorpg kinda setting. here is how id like to get it going:

-I want the large open world map to be devided into smaller sections (the frames) and i want 10 ish players to be able to connect in a room or instance part of the map with the possabilety of multiple rooms/instances running on the same server at the same time. so kinda mmo, but then deviding the players if there are more then 10 over different instances of the same map part. its kinda hard to describe.... let me try it like this:
lets say the room/instance limit is 10. and there are 10 players in that room. they all can see eachother. then, when a 11th person tries to join, a new room/instance gets created and he will be the only person in it till others join. and then when both are filled with 10 players and another person tries to join, another room/instance gets created, and so on. and that for all the map parts the map is devided into.
what would be the best way to do this? is this even possible?

-I want a good solid login system where the players register theyr info, then create a character with a job and costumize theyr characters apearence.
what would be the best way to write and request the info they enter and write with the creation of theyr character into and from the database?

-I want players to see other players as individuals with indivudual looks and the items and weapons they have equiped. ive seen some examples where players saw themself as a standard model, and all the other players as another model but i realy want to make players see others with different looks.
is this possible and what would be the best way to do this?

-And finaly, i want players to see theyr enemies synced with the other players. so that when one player sees an enemy, all the other players that are near him/her and in the same room/instance also see that same enmy at the same possition all in sync.
again, is this possible, and if yes, what would be the best way to do this?

And yes, i know, multiplayer is hard. Ive read allot and saw others asking questions about how to create a mmo and ive seen the "No dont do it, Its to hard" replies. as true as these answers might be, id like to hear somthing else. i do not know stuff about servers or how to code that stuff, but im intrested in knowing the right questions to ask to some people i know from the town here who do know network and code stuff. so, id like to know, what would be the best approach to do this? what questions do i need to ask them? how would you guys handle somthing like this? what script language? or maybe just lacewing? or a combination of lacewing and/or other programs? where to start?

sorry for the huge wall of text but im already feeling like im forgettting allot and im just trying to describe what i had in mind as clear as possible... i do not know allot about coding and stuff, wich is partialy why i chose clickteam fusion 2.5 ( wich i absolutly love!!! both comunity and the program) to work with.

so to sum it up a bit, i need to have some good sollid info on what questions to ask and what i need to do, or what the people i will hire need to do for me. all help is greatly appriciated. (and sorry for the bad english. ive tried my best to make it understandable but i have terrible dyslexia and english isnt my main language.)

Wow, what a challenging task.
Be prepared for a six-months work at least, and hope your motivation will keep up with your progress.
I see this as the biggest problem

All of what you request is doable, but any of those point would require an in-depth talk.
So we may better try to be general here.

Lacewing should be enough for most multiplayer needs in this setup, the only server-side scripting you would need is the one needed for registration,
you may better handle that with whatever application server language/technology you prefer working with,
as you would do any website-registration.

Then you can setup the dialogue server-app with the get object, to validate registration,
and then unleash the lacewing

If (it's not clear from your message, if I didn't miss something) your game is top down and you need full pixel movement (not gridlike)
you better send "vector movement" updates and NOT straight X,Y coordinates of every player, that would flood the system.
Dead-reckoning is not that needed *IMO* if you adopt a vector movement (send updates on speed/direction changes as I said above).

Room creation (first paragraph) is probably going to be the easiest task, as long as you keep track of what happens in a single server.

You'll have to think to how many players you think to target, as many player would require multiple servers, and so a much more fragmented and complex code to setup.

In short, there's a real bunch of things you'll have to do.
If you're willing to go on, dig down the forum - it is already full of every info you need.
