Those agencies are all like that. At least, that was my experience, working for quite a few, in several different states. They are just money grubbers, with no ethics. The agency charges more than double what they pay you. They make more than you do.

An alternative option for you would be to advertize your services on Care.com. Through that web site, you can find clients who pay privately, with no agency involved.

Whenever you walk into someones home to provide a service, it's a crapshoot. You never know what you're walking into. Still, I've known a few home attendants who found decent clients on their own. Ideally, you want to work for a client who is pretty well off. These agency jobs are mostly Medicaid funded. Hang in there and gain experience. There are nice clients out there. I hope things improve for you.
