Thank you both for the warm welcome. I may have some last-minutes to offer for liveaboard trips, but in my experience my Singaporean customers have a hard time getting leave days at short notice, and the last-minute airfare generally cancels out a lot of the savings with the liveaboard, so I don't usually bother posting them.
Generally speaking I package trips for individual divers according to the their needs rather than forcing the divers to conform to some prescribed package. Make sense? It costs the same no matter which way you do it, so why not do it in a way that makes the customer happiest? I've had several groups arrange charters, and those really do come out at a better rate, but again, I'd rather hear from the group and tailor the package to their needs than to simply post up an "offer" and then deal with people who need one sort of change or another in order to participate.
Really, I don't mind spending the time to prepare a package so that it fits like a dive glove to the visiting diver's needs.
Just let me know if there's anything I can do for members here. Letting you know where to find great dive site maps seemed like a good first step!
