You started a Game Studio without anyone who had ever made a game or done any work surrounding game creation?
Are you completely sure you're ready for this ?
You can either have your team learn to program in a language and library, or hire some programmers. The former is almost impossible, and the latter is very expensive (For good programmers whose code won't fall apart later in development).
Before you hire any programmers, however, make a prototype. If you have (an) artist(s), you should be able to create a prototype in Construct Two relatively easily (If it's Two-Dimensional). If its Three-Dimensional your programmer costs will be far more, and prototyping will be far harder, so I can't recommend any programs.
I hope your game turns out great, I can't wait to try it!
