Hey, My Sister,
There are several routes you can go. Harvest Time has a free institute program. I cannot testify to the qualitity of their materials. Here is their link:
http://www.harvestime.org/index.htmAlso, Freedom Bible College & Seminary, which has been around for a while now, and seems very good, is offering the opportunity to start satellite schools. This is NOT free, but worth looking into. They offer a good, comprehensive curriculum, but there is much propaganda for the director's views. Still, it's a good school, and they are accreditated. You will find the link for "start your own school" on the right hand side of the screen.
http://www.freedomministries.com/college.htmlThis one is for church groups, but I think anyone with 10 or more students can apply. Worth checking out. Not Free.
http://www.faithbibleinstitute.com/You know, it's perfectly legitimate to put together your own curriculum from good materials, and offer a certificate. We were going to do that the first year after we started New Covenant. I ended up getting divorced a year or two later, so I never got it off the ground, but if you are ordained and have a church charter (and especially as I know that you have a degree of your own), you can teach Bible study programs for a certificate, or even for an honorary degree. I did not want to offer the honorary degree, so I couldn't be lumped in with the document mills, but I offered a certificate for completing a very difficult course of study. It was going to be a comprehensive, graded program with a research paper, not a fill-in-the blank correspondence course. It's something to think about.
God bless.
