The plotmaster is pretty lightweight. I looked at one for similar projects and backed off. A lot of ground I was going to put into plots had not been cultivated in 100 years, and so clearing, plowing, etc. would have to be done before I could dream of using the plotmaster. It's all fun and games until you hit a rock.
What I found helpful was this:
Habitat How-To'sA lot of these articles were written by the biologist that came out from the KWDFWR to assess my property. Food plots are great, but they're expensive. A lot of the how-to's on that site are cheaper and do as good or better.
I've gotten the biggest bang out of things that are no-cost or low cost. For instance, just telling the hay-guy to be sloppy in the fence corners yielded a lot of new habitat in a hurry. Strip Disking is another good one. So is hinge-cutting trees.
Food plots? If you can get someone to disk or cultipack, just handspread clover or wildlife mix and then drag an old bedspring over it to bury the seed. I do that with my lawnmower or with my S-10.
