for the range of what works and how and the way things are managed,
google up the UXL group buy from about 3 years ago . ., it took awhile
Deholos (iirc the spelling)
person has to be the liaison to the manufacturer / builder
then it's IF? we can get X HT fans to commit to purchase, what sort of bulk price might the maker offer, say if we can get a demand for 100 or 200 or whatever X number of drivers
this of course puts some demand on the builder to deal with supply lines and time frames and provide realistic (as possible) delivery time frames,
then you get GB price
then a first come first serve list is generated by folks signing up and also making a deposit (50%) probably directly to the builder, he has to manage cash flow too...
then you wait . . .
in the mean time, work on room correction
so most of the "work" falls on the builder, managing lists and payments and shipping and on and on . .
so be cool about it . . .
