Need a simple CSGO gambling site

Was following a tutorial on YouTube but it is slightly outdated. I need someone who has knowledge of this type of website creation. THIS IS NOT A STANDARD website. Needs a deposit/withdrawal function. The video should be close to what needs to be done however it is slightly outdated and needs adjusting.
