By girl, I am assuming your wife. You will never get permission, or BAH for that matter, to do otherwise. The ECPI "campus" is just off of Ashley Phosphate Road by the Northwoods plaza. It is relatively close to base. Probably a 10 to 45 minute drive depending on time of day (i.e. Ashley Phosphate and I26/Rivers Ave lock up during rush hour).
MAP of said drive.
As far as financial aid and general advice: FAFSA, Live within your means, FAFSA, make a budget, FAFSA.
Trident Tech is a decent JuCo just down the road. They charge ~$105 per credit hour and most schools (Clemson, USC, UNC, NC State, The Citadel, CoC, Charleston Southern...) will take the transfer of credit from them. They have a few decent intern type programs with businesses in the area. Nursing and such. FYI, if the
masseuse gig doesn't work out. I took about 20 hours worth of Calculus and Calc based physics from them, transfered the credits to USC and had no questions asked. A lot cheaper than going to those schools direct.
