Hi, We would like to have created a website for a bitcoin lottery. Idea is the following: Users can come to the site and see how many bitcoins are in the pot (total amount of bitcoins). Users can upload bitcoins to the lottery (1% fee is deducted and send to other bitcoin adress). The amount that is uploaded will determine the change of winning. So that someone that uploads 1 bitcoin has more chance of winning then someone that uploads 0,2 bitcoin (example). Every week there will be a winner drawn (automatically) and payments will be made to the winner (minus 5% transaction fee send to other bitcoin address). So what needs to be done... website needs to be created. Scripting needs to be done. Automated payments need to be done. Users can sign up, login, view history and see the percentage of chance they have with their tickets. They can receive emails, and the winner is shown on the website until the next winner is drawn. So basicly an online lottery with garuanteed payout, all automated.

I have experience writing PHP that communicates with the bitcoin software. I have been involved with Bitcoin for at least 1 year now. I write secure applications and have deep understanding of web technologies. Of course, it will be best to develop this platform using the bitcoin "testnet" test network before setting it live. This way, we can use testnet coins which have no market value.

Hi I recently started my own after working for many years in Web Development industry. I was employed in HCL Tech. a month back. In around 9 years in industry, I spent 6-7 years directly working with client, taking requirement and helping others understand it. As this task requires planning and Architecture so someone with eye on detail is a must to have skill to make a solid foundation. Only solid foundation can help build a successful future assuming the concept is good. :) I am new to freelancing therefore to build a reputation, I need to start taking project at lower cost. At this price, you wont find person better than me. -- Sincerely, Satya

If you want to have explained to you then you are welcome to pick a time and date and i can show you through all the things that you need to consider when making it.
