Outsourcing post processing

Hi all,

In order to reduce time in CS5 and more time shooting (natural world, wildlife, expedition and lifestyle stock) I've decided to go with outsourced post processing i.e. initial cull, colour and exposure correction and potentially retouching for portraits.

I've shortlisted these:

http://www.colorati.com/ (most expensive - good reviews)
http://shootdotedit.com/ (in the middle)
http://www.fotofafa.com/ (cheapest)

Does anyone have any experience with all or any of them? They work out at around 20-30 pence per image which is very good considering the time saved in CS5 and ACR. They all have the ability to choose processing 'style' to make sure the images match your expectations.

For lifestyle and portrait skin retouching they all provide blemish removal etc. at an hourly rate ($50-70/hr) which seems a bit open-ended and could add up fast. Instead, http://www.pilotimaging.com/pages/services-retouch/ have retouching for $5 max. per image, a more controllable rate.

What are people's thoughts? Obviously some will say, 'you'll lose all your control' etc. but the truth is that most images for stock don't require enormous creative input in CS5 and just need a sensible, subtle colour correct.

Thanks in advance,

Alex.
