what are the better sites to find sales reps in US & EU

Alison's Contribution:

LinkedIn is one of the best resources I know.

Had a quick look at your web site.

I'm not sure if you want to contact distributors, retail chains or end users of stationery. Try a variant of

"stationery" + ~sales site:linkedin.com -inurl /dir

Try other search terms.
Try adding the city in which you'd like them to be located.

Hope this helps.
