It would be near impossible to get 1000 hours in just 10 months. I know several people who have timed out in a year - worked themselves to death to do it - and barely ended up having the entire month of December off. They all worked during their vacations, and most ended up saying it wasn't worth it...

However, in the event you did - you just need to maintain 3 landings every 90 days, so being out the last 2 months wouldn't affect your currency... If it did, they'd just send you back to the Sim. Not a big deal.

In my experience, with turboprop operators, you can do up to 10 legs a day. I used to work a regular 8-leg-a-day schedule, averaging 7 hours a day of flying. I'm not saying that's necessarily typical, but it is very possible.

Jet operators, average is about 3 to 5 legs a day, and about 3 to 6 hours of flying. That's just an average. On the outside extremes - 1 to 9 hours (actual) and 1 to 6 legs.

Legally (Part 121 Regs), no more than scheduled 8 hours a day of flying. 16 hours of duty max. 30 hours in 7 days. 100 hours a calendar month. 1000 hours a calendar year. Average month for a line holder is approximately 85 hours. On reserve, it depends on how short staffed your company is. I agree, average year is about 700 - 800 hours.
