Kris, On the drawing are the two end pieces the two drawer cabinets that are pictured? If so, my first thought is that the work surface is too low. Normal work surface height would be around 30" or so, about the height of the two cabinets. As for the top, you could probably find a veneered plywood and edge the front side with solid wood to save yourself some cost. Stain matching another species, such as popular would also save you some.
