Everyone is good on the pricing advise they have given you.
I have made crib sized baby quilts and Harley Davidson T-shirt quilts for clients. Crib sized quilts start at $120 and the HD T-shirt quilts, which are queen size, start at $350. I once had a client that wanted me to make a double sided HD quilt; we had discussed what exactly he wanted, talked over 4 days, he came to my house, and then, when I told him that it would be $850, I thought his mouth would fall to the ground! LOL! But, making a t-shirt quilt correctly, with cornerstones and sashing, is very labor intensive.
I also agree that working for $10 an hour is too low. Remember, if someone says they can go to Wal-Mart and buy a bed in a bag, and does not want to pay for a heirloom that if taken care of properly, will last them through to their great-grandchildren and beyond, then tell them to go and buy the bed in a bag. I have told them basically the same. Set your prices and stick with them. You are the one that is doing all the work.
Here is the HD t-shirt quilt I was mentioning above and a crib quilt....
