You might want to try babysitting on your own or even through a nanny agency which I do. Mom's Best Friend is the BEST.
They have a website MBF.com, You get to chose your availabilty and the clients and employees are nice. I worked for them fulltime for a few months and then went part time while I was finishing school and working as a MA during the day.
Good Luck and I hope this helps.
