Compile an open source iOS project and make changes

I am looking for an experienced iOS developer that can help me compile an open source iOS project and make specific changes. The project is called Element iOS. It needs to be built from the ground up with changes that have high priority. I already have a list ready, so the developer must be able to go over my list and work on it in a timely manner. The ideal candidate should have experience with compiling open source projects and should feel comfortable with making a variety of changes to the project. Thank you!
