Design a Website Mockup for a Market Place of CSGO

Hi everyone, Me and my partner are building a Market Place for people to negotiate items from the game ‘’Counter Strike GO’’. It should be a website functionally like “[login to view URL]” where players that want to sell their items can publish on the website and then other players can buy from the publisher. What I need? - Someone to design some screens we’re thinking based on screens that we already have (In attach there’s a photo of the home page) Most of them can be made by showing up a modal. In principle we're thinking at these screens/texts: 1 - Steam Login required 2 - Checkout 3 - Add funds 4 - Insufficient funds 5 - Ask user steam trade Url 6 - Failed trade offer 7 - Bot waiting user 8 - trade offer not accepted 9 - trade completed 10 - Itens to sell 11 - Confirm itens 12 - Failed 13 - Itens at sale 14 - Withdraw infos 15 - For security relogon 16 - Confirm withdraw 17 - Sucess at withdraw Work detail: - Can be done with or without coding it (Just tell me what you’re thinking at bidding) - Looking for people with experience and a portfolio
