Why can't you set a fixed payment now? You know how much your debt is and how much your monthly payments are, all you have to do is do an automatic transfer for the payment.
Sometimes a debt consol loan is not a good idea. You have to check to see what kind of rate you'll get because they might stick you with an 18% APR when your cards are only at 14-17% or if they have any processing fees or whatever. While a fixed payment might seem nice you can do that yourself for cheaper. Set up how much money you have towards your debt and pay minimums on everything except one. When that one is paid off, whatever you put towards that put on the next one.
I did just what your are looking to do myself. Although I did mine with the intentions of raising my score to get a good 0% offer. I got a loan and put my revolving debt on it, then I bumped my score to over 700 and got offered a 0% BT with 0% fee and then transferred the loan back to a card, after its all said and done I am saving a ton.
