I really want to work... BUT everything's against me!

I have been handed some great job opportunities lately, but due to lack of child care or transportation, have had to turn them down. I am going tomorrow to talk to a guy about working in his tax office, since I pretty much blew my chances of working with Liberty Tax, and he is paying GREAT. So, here's the problem... Chris is bringing Ayanna back on Saturday in his aunt's car, but has to take her car back to her that same day. I could easily take the bus there to work, but getting Ayanna and Noah somewhere for someone to watch them is next to impossible on the bus both ways... I'm pretty much resigned to the fact that I am just not supposed to be working at this moment. I mean, if I was supposed to do it, Chris would be here to watch the kids so I could, right? And as for now, he's going back to his grandparents to wait on a guy to finish fixing his car so he can bring it back here. No telling WHEN that'll be... UGH. FML!
I want to work SO bad, and this man's pay scale, while it is strictly commission, it's AWESOME! 40% of the fees would be mine... and average fee is $200... Hmm... you do the math. I feel so helpless right now. And forget daycare vouchers through DSS... You have to already be working for them to do issue those. UGH. This really sucks.
Any ideas? I'm open to suggestions!
