Greg, I think it is a good idea but maybe there is a better way.
Example:
I lost a dear family friend to breast cancer a couple years ago. I had some "Fight Breast Cancer" t-shirts made with all the proceeds being donated to research. This maybe a viable option for you to try. I always had a hard time asking people for money it definitley helps if you can offer them something in return for their donation.
Let me know if you need any help with something like this!
You know what, I have some t-shirts left as well, maybe I can ship them to you to sell for this cause. Although they are directed toward fighting breast cancer, interested?
Would anybody on here be interested in such a purchase for a good cause?
