I am the same as you, I like doing the tops, not the quilting. I finally asked several of the ladies at the local quilt shops if they knew anyone who does quilting, they gave me names of several people in the area. I bet you could find someone that would do your quilting for one of your tops. Normally those who do quilting don't have time to do the piecework on the tops and you could barter her work for yours, make sure you consider the fabric and labor in on the barter. If they don't need them I bet they know someone who would like a quilt.
Don't feel bad about yourself. God made us all different for a reason, we don't all like doing the same thing. Look at all the wonderful work you do, enjoy it and think of how many would like to be creative like you are.
