Just a quick question: can you give a sense of the scale of what is needed to finish up?  You mention a small budget, which is perfectly fine if the workload is also not enormous.

You're looking again?  Seems like your last artist was very undesireable.

I am available for however long you need me, but I charge by the frames and by how much detail is in each frame.  If you want to save some money, I can build sprite kits like this one: http://opengameart.org/content/multi-part-sprites-and-other-objects

Using a sprite kit can save time on animation but does not suit smaller art very well.  If you want basic pixel art, a frame-by-frame approach should be considered.  Since it is a farming game, I could make the game's trees, bushes, grass, and other plants.  I am capable of making a decent GUI design, as well.
