Hi Midge and welcome to the forum. Never apologise for asking questions - that is the very raison d'etre of this site, and the good thing is that other posters also benefit from your questions and the answers submitted by the experts and other posters.
I love the expression of ashtray and motorbike. I shall now add that to my vocabulary, as the chocolate teapot is getting boring!
With an offer of settlement in line with that originally pledged, and assuming that you have no property where you have to raise equity, I feel that you are making a good offer and that you do not need to do anything to enhance it. Why would you, as creditors are getting paid back much earlier from someone else's money.
I have put forward lots of offers like this and never had one turned down, so good luck!
