N2204F,
One way to find a good instructor or course for mountain flying is to contact one of the FAA Flight Standards District Offices (FSDO). The FSDO office would maintain a list of certified instructors and or courses that probably would fit within your time frame.
Try the FAA web site at
http://www.faa.gov there should be a link to the FSDO web site.
