IPod repair? Part replacement?

I have a 4th gen iPod touch (64g) and had the charging cord ripped from the port. The iPod will not connect to the computer or charge and when looking at the port there is obvious damage. Apple says the iPod isn't under warranty (I was lucky enough to send it in and have them let me know after all the hassle) They said they would repair it for $200 but I am looking for a cheaper repair, or to possibly buy the part and replace it myself if possible. Any help?
