I totally know where you are coming from. You could have been writting about my own situation. Only we have to come up with an extra $600 a month.
Not sure where you are at but often school bus drivers are allowed to bring their kids with them and you will only work mornings and afternoons. And lots of places will pay for the drivers exam you have to take too. The only catch is your driving record has to be just about perfect (at least here). I think the ads said they pay around $1400 a month or something too.
We're trying to cut back on grocery costs (NO junk allowed...only necessities), heating (saving up to put in timed thermostat..until then just turning it down manually) and power bills (using compact flourecents), and DH is taking in horses to train (which he loves to do but we always thought he couldn't make money doing...as it turns out he can...so its true what they say "do what you love and the money will follow"). As for getting children to babysit in your home I would just make up some posters to put up at the grocery store and post office and spread the word. Also...if you have the facilities you may want to consider taking in laundry...not sure how much you could make doing it but I think it would be a good thing to do in your own home...again I would just put up posters and spread the word. Or if you are a cook offer ready to cook meals. And I've thought about taking a plastic bag along and collecting empty bottles on our walks (my husband would DIE of embarrassment
but thats what we did for extra money when we were kids) and I guess thats assuming you live somewhere that has a bottle deposit refund policy. Oh and if you use long distance much a great way to save money on that is to buy the phone cards that they sell at 7-11 and other places...plus it has the added bonus of being money that you pay up front so you never get a shocking phone bill. The only down side is its a pain in the butt having to call an 800 # and enter a PIN every time you call long distance.
It sounds like you in a better place now actively trying to work things out and your attitude really is the most important thing. I hope that some of my random suggestions have helped
