Hello!
My name is Gregory Steam and I'm mostly a Steam API Developer.
In the past YEAR I've dedicated my career to one thing only, that's Steam API and Gambling websites.
So far I have created around 3 sites revolving around auctions and raffles, 5 sites for jackpots and 3-4 other type of CSGO/Steam API Releated sites.
I can create automated BOTS for your site, make a neat login / register system with live auctions.
I recently revieved the Valve Policy and I can easily create a site that doesn't break it's rules.
Check my portfolio (I'm not sure if it's 100% up to date) to see what kind of projects I've been involved in.
I'm a respected developer in a decent community of gambling websites, I can provide proof as I've made scripts/websites for bigger websites.
I realized I haven't talked much about SkinSanity, I know how the principals of the site works (websockets connecting to the server, etc) and I could easily create a system like that. The payment processors would be harder to make but I'd also look into that if you require it.
I can also provide you some great business ideas and marketing ideas of my own since I've talked to many people who run sites like the one you need now.
I'd require some money up front to pay my designer and get the project going.
Message me if you are interested!
