Yea, it's 1500 total, plus the other time reqs like XC time, 250 pic min (of which you can use some SIC time toward) etc. Most crews are getting about 100 plus hours a month, and close to the 1200 per year (part 135 rules) so it does seem like 10-14 months is accurate.

Overall, I've enjoyed my 5 years. 3/4 of it has been in the training dept, so pay isn't as bad. The flying is fun, the machines are tanks (when they're not broke), and your instrument proficiency and knowledge will excel.
Sounds like you may have an idea for extra income, so nice job on looking at all of your options. Good luck in your decision.
