Removing background from images

I am finding this too hard, I googled and found some companies that do this sort of thing, has anyone tried them? Is clipping path the same as deepetching. http://www.deepetch.com seems to be one good one, I also saw http://www.rapidclipping.com/Photoshop_clipping/home.htm and http://www.ezyclipping.com. Has anyone had any experience with this sort of thing. My catalog has over 300 images of jewellery and jackets with fur fitted on manequins due in two weeks, all shot on a blue studio background. Do I require alpha channel masking? Can anyone help please?

Do people really pay these sites to have backgrounds removed? "DEEPETCH.COM" thats crazy. 4 hour turn around. takes less than 10 minutes. thanx 4 posting that. had a hardy laugh. the 2 i posted were a rush job. a minute or so.

yea thats crazy just use your lasso tool around your image and basically cut out whatever and paste it in your blank canvas

i guess he didnt care.
