Anyone know where I can get a business style portrait taken for a reasonable price?

Thank you...

What business are you in and what do you consider reasonable?

Why all the questions?

Anyway, it's for a Mexican style resume, I want to get a job down there teaching English. My background is in engineering and physics, though.

Don't think it should cost more than $20.

Hope that helped...

Questions because I try to add context to portraits so they have impact. Not meaning to sound harsh, but $20 won't get my camera out of the case. I'd suggest that you go to boathouse row an hour before sunset with a friend and an iPhone. You should be able to get some nice shots with striking backgrounds for next to nothing.

At that price point, I think you will find yourself in:
1. DIY territory
2. J.C. Penny's or Sear's type package
3. Glamour Shot Groupon, taking only one photo

^^ Or my fave, a good friend who thinks he owes you one.

A webcam, a sheet for a backdrop, some lamps, and a friend to hit the button on the camera. :)
