UH No, No freebies. freebies just do not work. If she wants the images she can pony up the dough. Business to business is still business. Freebies are charity, hoping that you will get business. A better idea is to "rent" some desk or counter space from her place an album with good contact info and kick her a finders fee. If she wants to promote your business then let her get paid to do so, the same for you. But the images should be paid for and uage agreed upon in writing. That way if she never uses you again, goes out of business or has a prefered photographer you still get paid.
I am not sure why so many of you don't get it, but freebies rarely pay off. Business people respect your work most when they understand that is going to have a VALUE. Free is not a value. Discounts? Sure. Finders fee or referals, you bet. Get it in writing on your letterhead and she will respect your work and your business practices.
If not then you are just another GWC.
