modern states courses and Saylor tests or study.com?

I personally would do Modern States and get as many CLEP exams as possible.

I'd also check out WGU as a degree, rather than TESU - they have an actual BS in Marketing Management as opposed to just a BSBA with a concentration in Marketing at TESU.  Lot's more marketing and less GE - that's my preference.

I'd like to add to this WGU idea - since you have 6 children to support odds are favorable that you may be eligible for a Pell Grant, you may want to apply to WGU (free to apply) and fill out the FAFSA (a Pell could cover almost all costs - of this is the best school choice for this route) - you really have nothing to lose, might be the ultimate fast and low cost option
