Tshirts?

Alright mockingbirds, I need your help! I've been reading adoption blogs all evening and have noticed that many families are selling tshirts to raise money. I'm thinking I totally need to add some cute tees (for the grown-ups :) to my Mama Mockingbird line (after all, 100% of the proceeds from the things I make/sell goes into our "baby fund").

I'm thinking something cute (like the ones sold in boutiques), maybe with a favorite verse on the back.

Here's the part where you come in - Do you think people would buy them? And how in the world would I get them made? I have no clue! I need help!

Thanks in advance! :)
