I was going to suggest Matt, but I believe he may currently be sold out of the most recent batch. Now that he's fully moved and has the mill operational at the new property, he'll hopefully be getting more kits cut and dried soon. Those benches are massive! (he actually will...for a fee...take care of the finish milling for the tops. He did a video of that not long ago)

OP, Geoff at Adjust-A-Bench can provide a turn-key bench including the top if you want. If you go that route, plan a field trip to NJ because shipping the same would be, um...costly.
