My project is to create a Roblox MM2 In-Game Item Coinflip gambling website. I plan on including all of the available Roblox MM2 items and I'd like for the website to include a CoinFlip option and a Marketplace. I have a UI that's already been created and most of the backend is taken care of. My budget for this project is 350$ and I'd like to have everything completed in 1-2 weeks. As a reference point, I'd like the website to be similar to "https://bloxybet.com/".
