Before you browse through the pictures of my current stock below, it might be useful to read through this information. I am using jargon in the image captions due to limited space, so this information may be helpful.
First, 4/4, 6/4, 8/4, etc. refers to the thickness of the material. It is really pretty simple, but may seem confusing at first. 4/4 is about 1" thick when rough sawn. 6/4 is 1.5", 8/4 is 2", and so on. 4/4 usually mills down to about 3/4" thick, 8/4 can usually be milled to anywhere from 1 1/2" to 1 3/4" thick.
A board foot is the equivalent of 144 cubic inches of wood. I will usually charge by the board foot, unless I paid for some material by the linear foot (which is very rare). So, for 4/4 wood, a board foot is the equivalent of a 12" x 12" section. For 8/4, it is a 6" x 12" section.
I can also acquire special boards -- I make a regular trip to a regional hardwood dealer once each month, and can get wood stock for your project at that time, or I can make a special trip to get it sooner. If I take a special trip to acquire materials, my time for that will be part of the total cost of your project.
