I wouldn't consolidate, for the exact reasons Laura mentioned.
I know you say your expenses aren't totally accurate because Oz doesn't have mint, but if they are relatively accurate it looks like you have a couple hundred left over that you can throw at your debt. You need to eliminate your debt and free up your cash flow, and I would hit the debt hard because you are in hair-on-fire territory.
In this order:
1. you say you have a weekly income of $1172 and expenses (inc current cc payments) of $1092, leaving you an extra $80 every week (0r $300 per month) to throw at debt. I would cancel the cable (go without football for the year at least, sorry, debt comes first), netflix, music, cut down on coffee and do basic stuff to keep food costs down. How many people are you feeding on $400/mo? If its just you and EOW kids, you are vastly overpaying for food and need to cut that down immediately. Basically, do what you can to free up extra cash in your budget to put extra toward paying off the ccs.Cutting out the fat for a year should give you another $100 per month, for a total of $400 extra for debt. Figure out something else for the kids to do while they are there, as getting yourself in good financial shape benefits them more than tv and music does. Find fun free things or activities to do during their visits to keep them occupied.
2. Throw ALL extra money at cc #3 @ 21%. Currently it is conveniently the highest interest rate (correct me if I'm reading the stuff about cc#1 wrong) AND the lowest balance, so relatively soon you should have that down to $0 and can roll the payment you were putting toward it to the next cc. Getting rid of one bill frees up more money toward the rest of your bills.
3. After cc #3 is taken care of, then put the rolled payment toward cc #1, I think. I'm not quite understanding how you've broken out the into on cc #1 and I can't tell if it is currently generating interest or not.
4. Then roll the super payment from cc#1 to cc#2
5. Then with all other ccs paid off, roll again to pay off the last cc#4
Then once all cc debt is paid off, you can start saving that large payment amount because you've learned to live well without all the extras :)
That doesn't address the root cause of what got you into debt in the first place, however. Was it living above your means? Unforeseen unemployment? CC debt is a symptom of an underlying behavioral problem, not the actual problem itself. The only way to make sure you don't get yourself into this kind of debt again is to address how you got there in the first place and take steps to prevent it.
