Snowdog... yeah I would just walk in and look around. Get to know them and be sure to be clear on what you are looking for. At one time I was able to buy walnut locally here from a walnut log exporter but they don't allow that anymore. Dont really have a local mill anymore, wish I did.
You could hold off on a moisture meter if they tell you the wood is like 6-8 % moisture content and then let it get accustomed to your shop for a couple weeks before you mill it to your needs. If it is reportedly any higher in moisture then you would really need it to dry out more before milling it up. Find out what services they offer as far as planing and surfacing. Have fun..... those places can be alot of fun and the scrap bin can be a treasure chest for guys like us
