If you have all the money available for training, and start *today*, you are realistically about 18 - 24 months away from your licence. That will put you on the threshold of 30 before you get out there...allow for 5 years (depending on the economy, and the amount that you fly) and you'll be looking at 35 for an airline job...
What's your family situation? married, kids, child support? how attached to your current home and lifestyle are you?
The trick to it would be to move to a remote location where the company might pay for a staff house - then all you are covering is food, clothes and entertainment. Put all of the money that you might otherwise spend on rent towards your loan, and you'll probably be doubling up on your payments. cut back on beer and pizza (not that difficult in Fort Nowhere Lake) and you'll free up another $1-200/month...
The trick, as always, is to be disciplined about it...remembering, of course, that many have gone the same route, and struggled also.
BTW, there are lots of well-paying jobs in aviation that are not airlines....
Good Luck!
