Anyone have any recommendations/good experience with a pool remodeler in the SF Bay Area/East Bay? Location: Danville, CA /San Ramon, CA area

We have a 30+ year old pool/spa with old plaster that is stained and has a little chipping in the middle. Tiles began falling off last summer- got repaired.
Goal: white plaster like finish that is smooth and durable (prefer a longer lasting product) and new tiles.

Thank you
