When I did day to day subbing, I had my name in with about 6 different school districts. I was getting calls all the time and usually had to turn some down. Also, as I became more well known by the teachers and principals I started to have teachers request me personally. I ended up getting several permanent sub jobs through that. I can't give you advice about the day care because when I had my first child, I stopped teaching to stay at home. I know I've considered going back to work but the subbing wages here in Pittsburgh wouldn't even cover the cost of day care. The wages are anywhere from $70 - $85 a day and day care for my two kids would be about $1200 a month at least. Good luck with your certificate!
