Has anyone here worked for a temping agency and was given a week's notice that the source of their income was no longer going to be available to them?

I’m at a bit of a fork in the road. The temp agency I was working for on and off for three years has just informed us that they no longer have the county contract for the work I’ve been doing. They failed to mention that another company was granted the EXCLUSIVE rights to the work, meaning that the relationships I have built up over three years are now useless, because those county daycares can no longer use the temp agency I’ve been working for. I could sign on to the new temp agency, and have to rebuild the right to sick pay etc, or I could try to go independent and get paid direct, which would mean no reduction in my salary, and also represent a savings for the daycares I work for because, you know, no middleman-corporate-pig mark up. But, it means I would some how have to hustle and sell myself around for any eventual holes in my schedule. The current temp agency is eager for me to stay on so they can sell me to any independent daycares, but I feel very loyal to the ones I’ve been working with. Also, ‘2nd Job Tax’ is very high here and if I end up working directly for the county daycares and take the odd job with the agency, it could end up costing me money. If I was going to pay 2nd Job Tax, I’d rather do it working for a second county and work closer to home. Ideas? Suggestions? Shine a new light on this for me, anyone?
