I think your septic is off, I have heard $4000-$6000, so probably more like $6000 would be realistic. And that would be in rock. Do a search for septic on the forum, there was a post a while back by Menehune that covered the whole subject in detail.
Also, catchment and well costs are similar and you can do a well for under $10,000.
