Bobstay's suggestion is very sensible.
As to your working weekends, well, that's a huge advantage
Look, most working people work Mon-Fri, so obviously, that's when there's the most demand on aircraft and instructors.
During the week, you should get better availability of both machine and instructor, also .from their point of view. expensive assets are earning revenue,as opposed to costing losses to sit idle.
If I were a school, I'd go out of my way to keep a weekday pupil happy.
I'm just looking at this from a commercial aspect, so may be missing the blindingly obvious......if so, I'm sure the flamethrowers will "re educate"
