How do I find a grant for a disabled woman to start a business; that doesn't cost a fee to apply for?

I am disabled & am very low income, I am trying to buy a 34 acre property that contains a modern dog kennel & 4 rental homes. I want to raise toy breed dogs as well as offer grooming & boarding services. It is my plan to provide room & board (1 of the rentals) to a couple who would be my kennel attendants. Everytime I search for grants that say ';free'; there is always some type of charge (ie:shipping,processing, etc) Is there any kind of assistance that doesn't cost money? I mean, if I had the money for the applications, I wouldn't be searching for ';free'; grants/scholarships. Also, has anyone tried that grant book from off tv? Does it really work? Any other suggested places to try for any grants or scholarships?
