Definitely worth every cent! I sent them my latest construction worker series and they did an excellent job with retouching and image enhancement. I used to outsorce keywording to them, but now postproduction will follow as well.
Just have to decide how to spend my spare time....producing more images or playing with my wii??

I do not use sites that are not transparent and have no price information on the website and only by email request, there are no examples I can see.

I wonder if the quote I get is inline with other users, or if I am going to get the hard sell, I recently emailed asking for a price for a domain I wanted, but the price was not within my budget, I had wasted my time and had to block a number of follow up sales emails from the site.

What's the price tag for keywording.?..

In general: 2-4$, 2 for series. Title/description included.
They never will post it in public.
As you know, I'm into outsourcing now and I had thoughts about a similar service at a place where the wages are 35% under those of Chennai. But to be perfect and microstock-relevant, I should check all the output myself plus check competing shots at the sites to bump over them as to relevancy. Given that overhead plus the costs (included training) a price of 3$ is realistic.

Personally I would never let go the metadata out of my hand, since the right wording is vital for correct search info placement. It might make sense for volume uploaders though and image "factories" that run a tight shop.

The least the keywording services should do is put some examples online to have a quick idea of the wording quality.
