Lesbian Married Couple Looking for Sperm Only-DFW TX

HI we are Jenn and Amy and we are new to this. We don’t have they money for sperm banks and stuff like that. We’ve been married a little over a year now and we are looking for someone who can help us start our family. My wife Amy already has 2 children of her own but one has grown up and moved out and the other doesn’t live here. She can no longer carry a child and it’s the one thing I’ve always wanted. We are just looking for someone who can help us start our new little family. NO strings attached we just need sperm. This is our first time doing anything like this so a little help or being pointed in the right direction would be appreciated.
