Where do i find someone who would strip the old varnish off of a pine door and prep it for re-varnishing?

Call a furniture refinisher. I took 3 tables, old tables, that my grandmother owned. The dog used to pee on them, I almost threw them away, they looked so bad. On the positive side, they were well made and they had a storage drawer on them. They turned out beautifully! They seriously look brand new. I would highly recommend this. He charged me about $300 a piece and he cleaned the hardware, which also now looks brand new! Good luck
