Assistant to close USA leads

Hi, We are into mobile application design and development. We have a team of specialized app designers and programmers over Android and iOS frameworks. We are looking for sales representative or company representative in USA to close the mobile project leads. We will provide leads. I am expect to close at least 2 leads. My budget for 2 lead closing is 500 to 700 USD. I will provide more fee if more leads are closed. Thanks!
