There is a B777 in Saudi Arabia that pays $10,000/month for something like 6 weeks on/4 weeks off.
At the same time there are BBJs that pay in the $1200-1800/day range for contract pilots.
Airliners tend to command less money because there is a huge pool of qualified pilots who can do the flying.
The leasing companies via their contract agents and various entities that do the moving of airliners seem to pay even less, $800-1000/day and under is not unheard of.
Good for you to try and set the bar higher, but I think it might be difficult to get too much. The best thing to do is use the BBJ/ACJ international contract rates. If you get $1500/day plus expenses and per diem you've done pretty well for an airliner.
