I need a General Contractor

I have a partially installed sliding glass door. I need someone to finish the installment. It needs to be shimmed in, siding reattached, caulked , and inside trimming done. I am on a limited budget so would need an estimate to even see if it's something I can afford to have someone else do. I don't have a specific timeline though the sooner the better as it is the most convenient access to the backyard and I have two dogs that go in and out a lot!
Thanks!
