Hello!
Short and sweet: I'm finishing up a CSGO website as I write this. I'm just waiting for final payment before putting in the final touches. So, I do indeed have the experience needed to make a Ticket/Raffle Jackpot site that you're after.
I understand you're looking to have a custom design (naturally; all of my sites are custom and no two sites will look alike), as well as more than one game to offer to players. This is fine, as the site I'm currently working on has the standard Jackpot/Raffle game, and will soon have Flip-Coin and a Roulette type game. I would be more than happy to code any other games you would like to feature on the site - just let me know!
If my proposal no longer has the question answered, please just let me know - I edited this due to the fact that it didn't appoint all your needs, and it left that question out this time so I'm not sure if it was resent along with this.
I would be more than happy to talk more about the project, if you would like. And I would be more than happy to answer any questions you may have about it. Please don't hesitate to reach out to me.
Thanks in advance!
Paul
