Search Friendly Ads - Ad Marketplace Logo Needed

Looking for either .eps or .ai logo files for new ad marketplace logo

Search Friendly Ads

Tagline:
no tagline - the name is enough to deal with

Desired Color Scheme:
red

Desired Style:
clean and strong.

Accepted File Formats:
.eps and .ai

We are nearing the end of development and starting to focus on branding. We have a current logo that we threw together quickly that is currently being used on the teaser page @ http://search-friendly-ads.com

We would like to stick with "SFA" as the iconic focus of the logo, however, we are definitely looking for some creative ideas and concepts to create a memorable logo. the name itself is memorable - the product is exactly what the name is, it serves up search friendly ads on websites.

We are looking for strong, rich colors to represent our brand and we particularly like RED. That being said, we need the logo to reverse easily since it will likely be on a red background for the site design.

You can submit a "web 2.0", but that it not necessarily what we are looking for...

Please let us know if you have any questions, and thank you for your time with this!

Update:

While I do like magnifying glasses, I think that it is too "cliche" for the terms search. And, "Search" doesn't really represent what our product is. The product is actually an ad serving technology - the service being an ad marketplace; therefore, you're not using our product/service to perform a "search", it just happens to be part of our name.
