Write an iPhone application

Hello, I am new here and I have a small business in Brazil. I will need full support from a developer to help me put my idea on line. The person must use all codes as confidential, the product will need connect people, Geo localization, will need payment receivable and payment sends, prefer all automatically would be very nice to have an idea to reduce cost. I would like the APP user to submit his form, attached with documents for a background check, this user should fill a form informing his background and specialty. The user should inform his price to accept the job offer, should accept or not the offer, automatically he should be on hold for 2-4 hours if he accepts the job. and he commission should be paid to my AAP if he accepts the job offer. ( all cancelation from the user it should be penalty somehow after a warning). The company that will hire the user, should be able to locate the user at any place, the user close to accepting the calling, the company will pay a commission to the app for the service to find the user. Documents should be sent to my company. Please let me know, how much would cost this type of service, I have a low budget around 10USD hour, I would like to have prices for the platform, buy Geo or Use, how many hours will you need, prices for any relevant information that should we have in the project before I start.
