I'd do a search on this as this topic has been covered more than a few times.
But. One common place that you'll see recommended is Jerry's Upholstery out of Boring. I drove from Central Washington to have him make mine and I didn't regret a minute of the time I spent doing it. The quality and thought that went into it is top notch.
I'm a tall dude so I needed an extra tall one built and due to the design of my boat I also needed windows in the front so I could better see over the bow. Jerry built me a top that's towable and 6'4" tall and didn't charge extra even though it would've taken extra material. He also added front windows for a towable top and only charged me the price of the laminated vinyl ($300/sheet).
I'm now in year six since it was built and it's starting to wear. But. That's the life of the product not the design nor construction of the top which is holding up better than the top gun material. I fish 100+ days a year and there's only so many days of fishing or towing miles that a top can handle. I think I'll have another 2-3+ years left in this one before it's completely worn out which is longer than I'd expect.
He was cheaper than anyone locally in central Washington and I didn't have to pay any sales tax either. By the time I drove down and back I still saved money....

Did you have to haul your boat down or just the old top. I'm half way between Yakima & Tri Cities and am in need of a new top and would appreciate any suggestions.

I towed it down and you'll want to do the same so he can replace the snaps plus you can modify it as you see fit. But. It was absolutely worth it. Boat tops is all he does and no one locally had the same specialty.
He was a lot cheaper than our local upholstery shop and with tax savings I still saved money even with the drive.
