Ported intake gain?

What would be the rough price to port an intake?
to buy all the tools, what would the investment be? I will probably only port this intake.

I probably wouldn’t do one for less than 300.00 anymore but used to charge less because most of the time I was porting their heads too. Here are some prices for the tools needed.
30.00 for the burr I posted above
