HUGE Private Student Loan Debt - Any Way to Consolidate?

I have some insane private student debt, like six-figures big. It's a giant source of embarrassment for me. I realize this was my doing, and I accept that I'm going to be paying them back for a long time to come. As of now I'm current with my payments on all the loans, though the monthly payments are in a temporary partial payment setup. Once these temp partial payment periods have elapsed, however, unless my financial situation greatly alters the monthly payments are going to be far too much for me to handle, even with some help from my family.

I'm currently paying two different companies - Sallie Mae and AES - on two different repayment plans. My thought is if I can get them consolidated and under one repayment plan (preferably a 30 year one), though the monthly payments will still be high, I should be able to swing it. I have a good job, I live on a strict, tight budget, and I'm working very hard to grown my future financial prospects, but I really need someone to work with me to get they payments in a place where I can keep them in check.

Are there any avenues I have currently available to me to get what I want with loans pushing $200k or do I just have to let the monthly payment increases come and pay what I can until I go into default and they start garnishing my wages, and, heaven forbid, go after my father, who co-signed a good deal of my loans?

Please help.
