Something about your business name and logo are squashed/stretched.

Oh, I forgot, should I put my logo and website on there?

But our letters are always white, professional letters with our logo.  

Coming from 15+ of sales and marketing in corporate america I have found that best method for turning down sellers (which I just did about 10mins ago with someone) is to tell them the truth and explain why you can do anything with the property.

I've spent over 20+ years in corporate america on the sales and marketing side....and let me tell you the turnover is out of the control!

Also aren't we supposed to be making the letter personal with handwriting etc, like a bandit sign concept...but then how do you brand your company which is supposed to be a professional logo?

However a couple ideas.Increase the membership cost. 150.00 a year or 14.95 is way to small of a cost for the ability to market logos to non signed in members.

Make sure to include your logo on the mailers to brand your company and stick in their heads.  

YellowLetters.com is a legit source for what you need - and @Michael Quarles also offers a turn-key direct mail marketing program that incorporates his vast knowledge in REI marketing.  

We use mostly postcards, sometimes professional white letters (letterhead w/ logo), but mostly I like postcards because I can send 2 for the cost of 1 letter.
