Can you tell us more about your business plan? I know this isn't something that people talk about in public but I have some questions:
1. What's your budget?
2. What's your marketing strategy? There were a lot of similar projects and all of them failed, even serious ones.
3. Why do you think that your lottery system, even if it's better than traditional ones, will become popular?

These are the basic questions that I have because personally, I don't think that it's a serious project and will succeed. You didn't take care of your UI which plays a significant role between your and customers relationship.
