I've coded a text based mmorpg game in php. It's missing the layout and graphics. Any suggestions where to look for designers who have dealt with similar sites before? Also should I look for separate designers for layout and graphics?
Well you can try on freelancer and similar web sites. Also I think here are people that can do that for you.
www.freelancer.com www.odesk.com www.twago.com These are the most widely used websites for searching IT freelancers, and they each offer you an easy platform to deal with your workers. You should discuss with the prospective hire about how many roles they would be comfortable handling.
I know an excellent games designer. If you PM me with your e-mail address, I can ask him to contact you. /D
