Me and my husband just installed our vinyl liner. We are first time pool owners and just purchasing the house, we did not have the money to pay to have it done. We were surprised it was not as difficult as the pool companies make it out to be. It was pretty much me and my husband, the kids seemed to all be busy, the scariest part was the cutting out the main drain and the skimmers, but just take your time and I am sure you will do fine. Hooking up the shop vac into the skimmer or putting it behind the liner really helps pull out alot of the wrinkles.
