I need a website or way to sell my apps

I sell live apps that I make from the play store. I am open to suggestions and want to make sure it will work with the PPC campaign and funnel. Your experience with such a website is valuable, willing to pay for a consultation if you have such prior experience (with proof). I was selling on Flippa and my apps were selling (So there is demand and products work) but they take a huge fee for the listing and also take a success fee. And they can ban you any day for any reason which I don't like as they can kill your business in 1 go. That is why I stopped using Flippa and tried to sell on my open. So far I had little success with just social media or forum-based sites. I am thinking of making my own website like this [login to view URL] or [login to view URL] Start your bid with the word "Cat" so I know you even read it. Now, I was wondering if this approach would work as It is very hard to build trust with people on a website and doing branding is very difficult with a low budget. Is there any other better or easier approach like Gumroad where I can test the funnel first? Open for suggestions
