product quotation

Dear support,

I want to get a quotation for Device Expert, netflow analyzer and firewall analyzer i want to install these servers in four sites in different regions. should I buy 4 licenses for each product? or I could buy a multi installation license for each product. i have tried to use the online get quote link but it opens with errors so i didn't find any way to contact but through the support forum.

my maximum requirement for each product is as follow:
device expert: 100 device license
netflow analyzer: 100 interface license
firewall anlyzer: 20 device license
