Hiring an architect for a project

A relative of mine is looking for a good architect. He is planning to build a factory on his 2 acres of land so needs to know a well-known person who can do the stuff for him.

Since, his work needs containers to move in and out, he needs to make sure that the gate is set in such a way that a 40 foot container can easily move in and out keeping in view the size of road in front his piece of land. So the architect needs to look into the diameters etc. *complex stuff*

Can anyone recommend me a good architect which does all the factory map-making etc?

Secondly, what are the average charges for such a map-making?

NESPAK i guess.. They deal with huge projects.
