How would you do the following ?

We sell among others, trailer parts/spares to enable a customer to build his/her own trailer.
Now this involves every time such a customer walks in and wants a quote, to go thru the whole list of items and entering these on the quote form which takes some time especially when there are 5 people standing to be served.
I would like to be able to "recall/import" a pre-completed quote form with all the goodies on there and simply delete the inappropriate ones. That way I know that the quote is complete and the current prices are correct.
Bear in mind that the quotation number must increment and cannot be the same number every time otherwise I shall not be able to recall a specific quotation.

Hi Neville..............where are you ?
