1. Use a level and a pencil to draw a parallel line across the wall about 3 inches up from the floor. Measure down from this line, to the floor, and find the floors high point (if it has one), and mark a line at that point. From that high point, Measure up 34 1/2 inches and draw a level line across the wall to designate the top of the base cabinets.
4. If you decided to go with the piece of 1' x 3' lumber, now is where you will use (if you decided to go with the U-shaped frame, it will come into play after all your lines are laid out). Screw a temporary 1' x 3' support rail to the wall, aligning the top edge of the rail with the line for the bottom edge of the wall cabinets. Attach it by driving 3 or 4 two inch screws through the rail into the wall studs.
There are several factors that are going to affect the cost of your cabinets: cabinet brand, construction, wood type, and features. It is important to research all of your options. What you will find is that a higher price doesn't always correspond with higher quality, and some of the lesser-known cabinet lines will actually have a stronger construction.
