Hi Scott, and welcome to the forum.
First of all, well done for recognising you have a problem and wanting to do something about it.
You don't have to tell anyone that you are in an IVA. It is not published in the paper. It will appear on the Insolvency Register, but unless you know what you are looking for, it's unlikely anyone would see it.
I recommend that you call one or two Insolvency Practitioners for advice. You can visit
www.iva.com for a list of companies, or click on the expert link on the left hand side of the page here. The IP's listed on there come highly recommended.
Give one or two a ring and they will disuss all the options open to you and advise as to the best way forward for you.
