The land is considered part of your tools.
The tools themselves can be purchased at the GS (seeds, rakes, shovels, etc) on top of the Works which can make plows or wagons.
The bazaar would not do any payouts. Your profit will come when you've purchased the necessary land, RP'd out planting, growing, harvesting -- and then selling it, now you can sell to anyone, shops, actual people. Your $$ is based on the amount of time you put in and a healthy bit of common sense. The same goes if your growing animals. We want to see 'land, equipment, a proper place to stable and the time put in..' Thats why we have a conversion chart on the freelance post.
We do like to see logs of when your RP'ing it out and everything. Then of what your selling, like your own little business.
