There really are a lot of ways to make this work. 
Oooh, I hadn't even thought of that. You're right, there are a few "add on services" I can offer.
My kids are all grown and moved out now which means I have a nice, roomy home environment to offer with no personal distractions and can be available pretty much all the time unless I'm sick.
We actually have a small homestead here now and I sell fresh eggs, chicks and stuff from the garden so I may be able to sell a few things to the DCP's as well!
Again, thanks so much for your input!
