Non-Medical Home Senior Care--really "Kicking it around"!

My husband (an RN for 3 years) and I are really thinking about the huge potential of starting a non-medical senior care business (in their homes). I am in nursing school currently, and plan to finish either way, but this just seems like a true opportunity, from what I have read.

We have not even scratched the surface as far as Research and Development goes...But there is a definite need, and my husband (who is in home health care) sees it every day. He is also finishing his bachelors in Business Administration (FYI)....

Not only would this type of business be challenging, satisfying, and make a true difference, but also I believe the monetary and growth potential is huge.

We have looked at several franchising opportunities (just browsed the websites), but not sure if we can afford something like that at this point in time, since we still have, well, sadly a negative net-worth! But I would think that there would be all kinds of small business loans and other helpful agencies/people???
I dont know, I just have that "entrepreneurial spirit" and we both are very caring, compassionate, creative, and yet...business oriented! Seems like the perfect fit???

Any help to get us started in the right direction would be greatly appreciated. Or perhaps point us AWAY from this direction! Thanks in advance!
