Any single parents travel with children?

Hi all! I'm thinking of taking a travel assignment this fall. I have two little boys, ages 4 and 7. I homeschool them, so school is not a problem. I just wonder, can I expect help from the agency in finding child care, such as referrals to nanny agencies etc.? Has anyone else been successful with traveling as a single parent with their kids?

Also, I'd appreciate if anyone is working with a truly exceptional agency can PM me and let me know who they work with and what their benefits are. I definitely need free private housing, two bedrooms would be ideal. I need to take my dog also. I would like utilities to be paid by the agency, and pots, pans, linens, furniture, TV, etc to be included. If I end up traveling across the country (I live in NC), free airfare and rental car would be nice. Does anybody work with an agency that provides all this?

Thanks in advance.
