Hi There,
I am an experienced game designer and would be happy to design a game for you. Please be aware I am a game designer, not a graphic designer; I design game mechanics, not graphics.
I know what makes a game fun and am able to apply this knowledge to simple games that are easy to pick up and put down, and complex immersive games that take a while.
I'll raise your idea to a few concepts from which we together select the best. I will then design it further to a production ready design with an accompanied game design document.
The game design document can be used by you, your programmers and artists as a reference to develop the game.
Best regards,
Erwin
