If I pay off one thing that has went to collections already will it make my credit score go up a little even?

It will sure help. Smart thinking. 👍

I deal with debt collection companies every single day. You call them BUT do not acknowledge the debt at all, you ask for a copy of the original contract, than you can make an offer to settle of around 30% of the debt or pay off at $5 per week with no interest, no charges or fees to be applied to the account

That really depends on other factors. How many other debts are in collection and what do you owe on the one you are looking to pay off?
