I have a few suggestions, but would rather discuss off the forum....if you send me a PM I can send you a few that I use and a few that I don't use

There's a place in Manchester nh called ceder crest cabinetry. I can't comment on final product as custom was way over budget for us. But through the process of quoting they were fantastic and helpful, never laughed or brushed me off even tough my budget was clearly nowhere near their quote. We ended up using lowes for cabinets and Home Depot for quartz (both in concord nh). I know big box stores are not popular here but we had a good experience with them.
