Hey.
Firstly i am not sure how much of Experience you have with Mu Servers configuring/coding and/or server setup/website/antihack etc..
Anyways about your plan:
Buy the files from MU Engine -- $280+
- I never hear good words about mu engine.. so i dont recommend it either.
- Good files on the market are : IGCN,X-Team as far as i know.
But also remember it depends what features you want in game!
Get 2 Admins for the game -- $2,000 / month
- you really wanna pay 2.000 a month for mu admins? hire me in
No but seriously.. it sounds professional but can you define admins for the game? are they game masters who do events and such or admins who fix bugs/help config the server/ add events/ spots etc? 2.000$ is not a joke and i wouldn't want anyone to get tricked so beware...
Get 2 customer support -- $600 / month
- same thing here.. beware who you hire and be sure you make CONTRACTS for them to work professionaly with signing and full address etc... is very hard to trust anybody nowdays just because someone says 'he knows'
Get A web developer to do the website - $300 one time
- you can buy muonlinewebsCMS or DmNCMS for cheaper price. Or even use the nulled ones.. or yeah sure 300$ for a fresh nice muonline web with integrated forum or / and facebook registration etc. Website is worth it.. but just as i said there are cheaper ways with websites that are already out on the market for better prices.
On call game dev at $50/hour
if you have game developer then u wouldnt need to get any premium files, cus probably a game developer (for the server files and client side) he will find some existing open source files like IGCN/muemu season 6 and work with the source and thats it. But be sure you are hiring a MU Developer cus they know how the mu files and sources work.. other freelancers will first have to learn and that will cost u even more.
PS:
you will need antihack which for sure will cost around 25-35$ monthly
then you will need advertising plan strategy (if you really going serious serious)
then you will need a good hosting server and webserver
you might also even need a Graphic Designer (for your web) and maybe even for game content/skins etc
and there are more optional things...
Someone who will write the content.. for the website news/announcements/events etc. (or u do it)
nowdays you can make a server for entirely free honestly, ofcourse some features might be bugged/non working/disabled but it all goes back to what server are u making.
So what do you really want? you decide !
edit: which experienced mu admin adviced u this plan? if u can tell.. if u can't maybe PM me
i'm really curious.
