Negotiating settlements yourself will help you save money on retainer fees, commissions, etc... Rememeber, different creditors have different criteria, all of your creditors may not want to settle and wait until charge off and get a collection company involved. You can also settle with collection agencies as well. I believe PayPal may not settle for much but try it. JC Penny, may refer their account to a law office when they hear settlement but it is worth a try, I have seen this happen in the past. Wells Fargo may react the same way as JCPenny.
Discover will refer the account for collection to Zwicker and Associates and they usually only offer to settle accounts for 70 cents on the dollar, meaning a 30% savings.
Looking at your total debt I will venture to say by the time you are done settling all accounts you will save no more than 4 thousand dollars even if you join a settlement program. You will be better off negotiating the smaller accounts first and continue making payments on the higher ones, this is a good strategy if funds will not be readily available to settle all accounts at once.
Remember, late fees, interest rates, will continue to accumaulate on the unpaid accounts, these added fees are to be kept in mind as they will become part of your balance when you settle.
Great coaching is available out there, best advise on your total debt, pay no more than $500 for anyone to coach you on how to negotiate tyour debt. You can do it, there is no need to be a negotiator or a salesman to settle your debt. Simply read up as much material available regarding debt settlement. Good luck.
