Hello, it seems you've done this so far all by yourself and can't blame you but here are the thing you could do in order to improve your auction site:
1. Add a favicon intended for your website
2. Use your own logo in the header (which your doing it already as you mentioned above)
3. Buy a template for your site (it would really be worth it and you could easily customize it)
4. For payment gateway: Use anything except Blockchain.info API itself (literally)
Update:I don't think that WeBid wold have any premium templates, its a very outdated script.
Do you understand what you mean by saying Blockchain API itself literally?
I think you mean not using Blockchain.info API
Anyway, apart from that, I agree.
It looks very bad and old.
No I didn't meant for WeBid template, I meant for any premium template possible (Not restricting to WeBid if there are any)
Sorry, corrected my earlier post, I meant Blochchain.info API
