Along with a cover letter that is personalized for the particular prospect, 2 copies of the agreement, both signed by me, along with a return stamped envelope are included.
Might as well get it all on the table up front. Also, my agreement is multiple pages and I check off the services they want a bid for. By them getting the entire "template" agreement, it allows me to display to them other services we offer that they might not know about. or have an immeditate interest in.
I built the agreement from the template that Sean here has for sale. Its modified quite a bit but his template was very helpful.
