I need an APP developer

I hired one, but he is useless. I need to hire someone who can follow through on a simple APP and deliver. I have an apple Developer account ready to go. I need an Android APP and Iphone APP. 1 APP/2 platforms.
I have samples of similiar APPs already created for reference. Need this ASAP. or if anyone knows a good site or any information on someone who can follow through PM me.. thanks!
