I can confirm that OP is Paul Coleman.
He sent me identity verification.
The problem is , I don't have sufficient trust to make this mean enough. Check
this thread for a more reputed person to help you out.
I've been convinced that this is legitimate , but you will need more to make it work :-
A - Flesh out your idea
1- I'd like to point out that the idea that you will reach 500,000$ is insane. The most reputed casinos have had maximum winnings of around 200,000$ in a single bet.
I'd say that the maximum you should aim for your first draw should be 1000$ (which still seems higher than the optimum ~200$ I'd feel best)
2- Discuss along with your team/business partner on how everything is going to work. This does not have to be set in stone forever , but you need to have an idea on your first lottery. How many tickets will you sell ? How much will each ticket cost ?
B -Here is my personal opinion of what changes you should make :-
1- Remove the pay with Bitcoin option. Don't take payment without setting anything up. If one single well reputed scam-buster comes and leaves you a negative trust remark , your forum account and website will permanently lose any credibility.
2- Make your FAQ look more professional.
Is this a joke? => What is the International Bitcoin lottery ?
Is this legal? => Take down this section. It makes your company seem illegitimate. You can hire proper lawyers later.
Is this another Mt Gox? => How can I trust you ? / Can I trust you with my Bitcoin ? (Explain on how you have measures to protect peoples' Bitcoin.)
K. How often is there a draw?
When is the first draw?
What's the Jackpot?
What happens if I win?
Change all three of these together into a separate tab or page of your website.
That page should be called "Game Information" and should have all the information about the workings along with including the amount currently invested in tickets and previous draws.
You will need a house edge of 0.5-10% , which will be used for maintainence and for your charitable contributions too.
50% to one winner and 5% to 10 others sounds like 0 house edge. ( 50% to one and 5% to 9 others would be good)
What happens if I win?
This section is okayish.
Can I remain anonymous if I win?
No.
Bitcoin has anonymity as one of its basal pillars. You cannot remove anonymity.
This may help you prove your authenticity , but it would help more if you utilize a provably fair system like on-the chain betting or instead use a live random.org drawing.
Which kinds of causes will you be supporting?
Good section.
Cool, can I help in some way?
Okayish.
C- Setting up security , from you and for you.
You need to set up a reliable system to ensure that you won't get "hacked"
Secondly , you will need to use an escrow or start really really small.
There are a tonne of escrows that you can use , but it shall make expanding beyond a certain point almost impossible.
TL,DR; I've received your identity verification , but before you can start accepting Bitcoin , you need to think out your idea in more detail , express it properly in FAQ , create a new "game statistics" page and get an escrow , or start out at a much much smaller scale than 500,000$
