Mortgage Company Looking to be updated....something more current

http://www.k2lending.com

K2 Lending is a mortgage company based in metro Denver Colorado. We have been in business for over 8 years and have an A+ BBB rating. We advertise on several websites and are looking for an updated theme. I could go either way on the mountain theme. Maybe something a bit more tarketed to real estate with a move to current graphic trends.

Buyers, Sellers, Realtors and anyone looking to purchase or refinance a current primary, secondary or investment property

Please see website for current rendition...www.k2lending.com

Not sure what requirements I have from a technical standpoint except one of our advertisers requires the following:
• Exactly 125 pixels (width) x 45 pixels (height)
• Format – GIF only
• No flash and no animation
• File size – 2k maximum or less
• logo trademarks or registration marks must be included in the file (™ or ® marks)
• Must be on transparent background with no border
• No 1x1 pixels for tracking allowed

This is a good start...but I do need a logo that is customizable after the fact.
Different websites require, different parameters.
