Crowd Project

Myself and business partner try to open a local business similar to [login to view URL] Yet we were thinking of having two instead of one language with a potential 3rd and 4th coming later as the project grows. We would need someone to do the creation and bug fixes the initial setup plus the bug fixing and potential further developments in the future. The ideal person would be able to handle the graphics and the coding part but not necessarily it could be two people as well. Kindly submit a all together fee including trouble shooting and estimated time line til completion. Programming language is in general up to you but it should make sense and easy to adjust/improve later on. Kindly mention the programing language you would like to use. Thank you for your response in advance.
