Greetings from Canada ! :)
I'm currently working in my own Unity 3D Game studio and i've been developping mobile games for 2 years. Your project seems pretty simple and it should be done in few days. As I said in my profile, I'm not an artist. I cannot provide exclusives graphics/music/sounds effect/animations etc. BUT, We can certainly find what you need in the Unity Asset Store for a really cheap price! :)
Note that the price I gave to you doesn't include the price of the assets since I don't know what you want.
Until then, thanks for considering my offer and I wish you great success in your project ! :)
Hope to work with you,
- Fred
