I have tried to figure out how to make normal maps for this tileset and have kind of hit the wall after finishing the very basic tiles: dirt, sand, rock, brick, transition from dirt-sand, dirt-rock, sand-rock. 

Since the normals set is incomplete I have decided to put it up as a free to download pack for now. If I ever wrap my head around how to make all the grass, snow etc. look good with normal maps, I will finish this pack and add to the full package.
