I own and operate a website pretty much on my own. I have a few
thousand stickers that I would like to offer to my visitors for free or for a
small cost. I do not want to deal with the payment (if I do charge)
and mailing process though and was hoping to find a company to do this
for me.

I'd imagine there are quite a few companies that offer this kind of
service, but the problem is that the volume wouldn't be that large and
neither would the cash flow (not doing it to make a profit) and I don't
want to pay too much for the service.

Are there companies that can handle this for me at a reasonable cost?

Thanks!

Note: I'd like to go the Cafepress route, but they unfortunately don't
do diecut (cut to shape) stickers and the stickers would be fugly if
they weren't. A company similar to them where I provide the stickers
is EXACTLY what I am looking for.
