Hi and welcome to the forum.
First of all, please try not to worry - easier said than done I know! You've taken the biggest step by admitting you have a problem and doing something about it.
Do National Debtline do IVAs or do they refer you on to an IP? I'm sorry, I don't know a lot about them. You can always take advice from another couple of companies to make sure that you are happy with the advice. You can find details of companies on
www.iva.com, and the IPs who post on the forum are highly recommended.
If it makes you feel any better, I thought I owed about £35k, but it turned out it was nearer £65k!
Don't worry about bailiffs and CCJs - if you are going for an IVA your IP can apply to the court for an interim order if it looks like this might happen.
Good luck, and please keep posting x
