put a wanted ad on your local craigslist. That's what I did. I called our 4 local pool stores, and they all wanted at least $800 to do the job
I put a want ad for someone (with AGP liner experience) and in about 3 days I had a reply. The guy came out and said he used to install liners for a local pool company, but quit. Anyway, he came out on a saturday morning with 3 of his buddies..and they leveled the pool sand, made sure the pool was totally in round, mounded a sand coping around the edge, and installed the liner, had water truck come to start filling the pool, and then once the liner was set..he put on the top railing edge and post caps on and installed my intake and returns.
Cost.......$425.00 this was for a 33ft round AGP
