Salt Water Conversion - quoted $2500 for a 10,000 gallon pool

Hey everyone! Is this a reasonable quote or too much? The pool guy said to go with a bigger system to get more use out of it and is going to install a sacrificial anode for $2500 in FL, but I feel like that’s a little high. How big of a system should I really get for a 10,000 gallon pool?

Thanks so much!

EDIT: I managed to find a reputable company to install it for $1,724 including the salt. It’s a Jandy TruClear 35,000 cell. Seems like a much better deal!
