You need an actual, legitimate logo. It's hard to sell trust and authenticity when your branding could be replicated by a Photoshop amateur in under a minute.

The seal is in desperate need of a redesign, as well. I wouldn't be willing to put that on any of my websites. I suppose that it could get peoples' attention, in the same way that running ads designed in Microsoft Paint can increase clickthrough rate. It just doesn't sell trust and authenticity.

Hope that wasn't too harsh, but you're offering certifications. Your brand matters much more than most, and you don't have one.

My advice: Go to Elance and get a lot of mockups.
