Stna???

I don't know if this is the right place to post this but here it goes anyway. I am 56 years old just remarried. I had my own businesses before this year for 3 years right after I graduated from college with a degree in Liberal Arts Ihad to close them and go to work for a really yukky company that I hated. I am not with them anymore and really do not want to work for anyone. I would like to start ( I dont need health insurance so I can do this) a transportation service for the eldery but am at a loss as to where to begin. I can get my STNA and all of the other things that go along with it CPR, bonding, insurance etc. but I want to make sure it is worth it first. I wanted to know if anyone has ever done this or if you have done this for a company like a temp or independent contrator and how much do they pay. This is kind of disjointed because I am really not sure to go about it and any help would be greatly appreciated. I can also get my STNA in Toledo thru the board of ed for half price because I am over 55.
