Gucci Satchel Handbag Brown-needs Repaired

Hello everyone! This is a Gucci I have had authenticated already. As you can see the outside has minor issues however, the inside lining needs replaced. I am not a purse repair person. When I purchased I didn't realize the damage inside. I included a picture of my white desk to show that just handling for pics, the peeling is coming off. I contacted Gucci and repair costs are about $450, not sure what repair would be for a new quote, mine is about 3 months old. If you are talented and have the time this would be a great project!!!! I am trying to just make my $$ back that I purchased it for. Questions please let me know, offers always considered. Comes from a smoke-free and dog friendly home.
