Build a Website - Bitcoin Based

I need a designer/developer to build a website for us. Our business idea is following: 1. The concept is bitcoin investment. We offer 50% profit return to our customers in 15 days who will invest at our platform. 2. The minimum investment is $5 and maximum investment is $5000 3. The user should be able to sign up on our website with a unique profile. 4. When a user intends to invest, a new bitcoin address needs to be generated, linked with out bitcoin wallet. 5. The investor should be able to track is previous investments 6. The investor should also be able to calculate the return on his investment. For example; if he is intending to invest on 1st June, 2016; before investing, a summary should appear that he will get $150 back on 16th June, 2016. 7. The website should also ask for the btc address where investments are to be returned. Any questions, please PM.
