I Need a a custom Rust Betting Website Made -- 2

Hi, I'd Like someone to Help me create a betting website for steam games such as rust, I'd like it to include games like Crash, Roulette, and Coinflips. If possible I'd also like a levelling system where you can earn some rewards for depositing more items I have some very tempory png's as placeholders here while I make up some new ones, I'd Like to keep the price down to around $50 but I'm willing to adjust depending on what's needed.
