I need an iPhone/iPad app. I would like it designed and built. I want to create an app where people can easily swap items with a fun user interface. I have many business graduates on board but require an app developer. I also have screen shots from a graphic designer of each screen of the app. I require a developer to crate all aspects of the app. We can pay weekly to cover the cost of progress but would prefer to keep the initial costs as low as possible and therefore are able to offer a 12.5% Stake in he company. Please let me know why I should have oh on my team and what your weekly rate would be.
