How do I start an online training web site?

Wednesday, December 9th, 2009 at 6:24 am

I have written many environmental health and safety training classes over the years and I teach them in the area I live. I would like to branch out and offer these classes online where anyone interested could make the payment and then be directed to the test. Upon successful completion of the final exam the person could print out a certificate.
Thank you for any help you can give me.
