Trusted SSL?

[intrigue]

I need 2kb on a trusted SSL (verisign, thawte, ect).

I am using PayPal to accept payments via the web. PayPal's security certificate is issued by Verisign and is trusted by default in most people's web browsers.

PayPal offers the option of including my logo in their payment processing pages, but...
Although I do have SSL running on my server, the certificate is self-signed and not trusted by default.

If my logo is located on my non secure server, there is an alert upon opening the payment processing pages that "this page contains both secure and non-secure elements" and gives the user the option of not displaying my logo.

If my logo is located on my secure server, there is more than one alert saying that my certificate is not "trusted" and such.

I know that it really doesn't matter if my logo is being sent to visitor's browsers via SSL or not, but these alerts may cause visitors to question my credibility.

So, anyone who would provide me with a very small amount of webspace that is secure and the certificate is issued by a company that is trusted by default in browsers would be of great assistance to me. I would be very appreciative.
