iOS Developer, long term projects in mind

Hi, I am looking for an iOS developer to help make games as well as re-skin and tweak future games. This will potentially be a long term position, with many projects coming up for the right person. For now, the project is below.

Make game similar to color switch.

I’d like 4 “colors” that can be changed based on theme. And to have the “ball” or character to be changed as well to 4 different characters (image based). When the user its the screen, the character jumps and falls down slight. The more times the screen is hit, the higher the character goes.
For re-skinning
[] Have the ability to change the colors of the obstacles (square, circle, triangle, etc). Maybe name them color1, color2, color3, color 4, and set them up later.
[] After each obstacle, have a “change character object” that will change the character to another character randomly
[] Support for Ads
[] Support for in-App Purchases
[] Have “Lives” for each time they play hits the wrong color and dies.
[] Instead of stars, collect “pandas”, like this
[] Have coins
[] Audio for when “jump”s
[] Audio option for collecting Pandas
