What our subs are saying:
I love the SubAssistant. It works seamlessly with SmartFindExpress. I no longer have to waste my evenings in front of a computer hitting refresh. Now I get a text message and log in from my Smartphone to grab the job. The result is three hours of free time to play with my son and better job selection. Thank you!!

I would like to thank you for offering such a helpful program. I have been very happy with the your service and would recommend it to anyone.
— Shannon, MI
This is a must for any substitute that uses Subfinder. I have gotten 2-3 times as many jobs per week since I started using this service!
— Jason, South Pasadena, CA
I was told about this site about 6 weeks and in the last 6 weeks I've subbed more than I did all last school year! Absolutely LOVE this service.
