Multiple hammock purchase/DIY

Trying to come up with multiple hammocks for friends and family. If I go the DIY route for the hammocks what would be the most economical/cost effective route for suspensions if I did this say for about 6 hammocks?

Also I will have to do multiple bug nets and tarps.

I was thinking about a WB Super fly x2 and making a Fronkey bug net. The Kelty Noah 12 appeared to be a consideration but I have heard people have had problems with them. Most of the camping will be car camping to start with and may include some kayaking. Eventually will get to the backpacking.

Anyone know of vendors that have discounts for multiple items?
