I will give the chemicals mentioned here a try. Both of them. And report back.

It might be a week or so. We are getting four inches of snow tonight and temps in the low 20's next week. But after that I should have some good weather.

And I have plenty of outdoors to work in. My nearest neighbor is about a mile or so away so there is no chance of upsetting them.

After that on to looking into having the work done by an outsider. My situation is that the nearest place to me doing this sort of work is about 100 miles away. This is why I was wondering if I should get into it myself. The only customer I would have is me, though.
