First, as discussed here on Travelfish, you can 'do' the journey on your own (if you choose).
Any of the tour agents offering the Saigon - PP leg, can book you on the reverse. In the first instance, try emailing and asking the price.
I see this mob advertise a PP - Saigon tour and the tour layout has better options than some cheaper ones. I don't know them so can't comment on their merit.
I have just returned from a month trip which included a 2 day 1 night boat trip PP to Saigon. This and the 3 day 2 night can be booked from your hotel or one of the many tour operations at street level. Our trip cost $27 usd and included, boat, accom (Chou Doc), visit to fish farm and minority village and bus to Saigon.
Hope this helps
