MCESaint…...I totally get it....when work demands and child care needs collide....it is a parent's nightmare! I was a single parent, for several years...so, I know exactly what you mean....
Just a suggestion, for the short-term, that might work---If you were to call an agency and have someone who can come and stay at your house....someone who is bonded......for the short term basis, that would give you a bit of time and space to make more permanent arrangements. That is the most expensive option, but, probably the fastest....
