Do professional photographers outsrouce their image enhancing needs?
Requirements such as retouching, color correction, composition, image
manipulation. - how viable are companies that
offer this service?

We are at professionally doing grapics work, so your requirement of
retouching images, color correction, compositing & manipulation of
images...and much more .. with images can be done with excellent
results that will be like professional work.

secondly,companies offering these type of services are lot capable of
doing that but they cost a lot.

But, we are providing it at a much affordable and competitive rates.

photographers do that all the time. some have people who work for them
that do this type of work. I am a freelance graphic artist and web
designer. my web site is www.yoxim.com. My prices are posted on there.
Depending on the amount of stuff that you need done, those priced
could be negotiable.
