Mel - Take a look at this video explaining the treatment plan. It looks to me like your most cost effective treatment is a complete extraction on the lowers with immediate dentures. Typically, I schedule for extraction and immediate delivery with a 1week followup for adjustments and then follow-up as needed.

I know we work against your schedule, but I still have the same options M-Th 8-5pm, so you might need to take a day or two off from work.
