I can't help you out with your sand question, but I can with everything else.
GCAS auctions are always held in April & October each year. The Swap Meet is usually in February, but not this year since GCAS is switching event venues from The Oasis and was it rescheduled for May. There is only a meeting this month.
I have MTS's. How many do you need? I'm pretty sure I can get some duckweed pretty easily too.
