Hey there! I'm glad so many people are interested in the PokeMall. It excites me. lol But in any case, basically, you can sign up and create an entire shop. You get to add Pokemon, Items, designs, and more to it. You can choose basically every option you can think of to customize your shop(s). You can even make individual trades if you don't want to make an entire shop for like 3 Pokemon. There may also be premium options like having your shop/trade advertised on the entire site, etc. etc. You can definitely help out! For right now, all you could do is maybe provide some ideas - I need these, because they are what makes the site better for the people that actually use it. Now, I'll actually use this site as well, but that's beside the point. When the site starts development (in a few months), I'd be more than happy to make you a beta tester. This would include testing it in different browsers, using a test account to test every feature, etc. etc.
