There are a variety of prices out there for portals in bides in Iran.
This is because, each company on the business or government has
different idea and requests, which thinks, can be or must be covered
by a portal.
So the a portal  RFP in Iran are usually wide range and covers many
systems like Content Managements, Data ware house, collaboration
systems and even Finance Systems !
This made the IT Companies confused and lead to very different prices
for a single portal project.
The technology is also another main issue which sometimes is not
highlighted in RFPs and makes the case worth.

PHP portals are VERY cheaper than java ones
