Hi,
it might be best to register a new account for your personal things.
All you need is another email address, which you can also link to your PayPal account.
Just had a look at some of your items and they are really nice.
You do, however, need to register as a business on eBay - as you are also referring to your website I think you'd agree that you are a business seller.
