Unfortunately my site is just for info and links to http://www.independentpressing.com who handle the business. Visit the site, then contact mailto:email@example.com for a proper quote. It is probably going to be prohibitively expensive to press just 10 records as it is likely that you’ll have to pay for a minimum of say 250! And there are all the upfront costs like getting it cut and making the metalwork. Maybe £250+!
Visit the site, then contact mailto:firstname.lastname@example.org for a proper quote. Maybe it would be a better bet to get a 10" dub plate cut. That could cost maybe £80 each, but they do wear out after a few plays. I think Porkies cut them on a Friday afternoon. Or a better solution now is an everlasting dubplate.

Sorry to not be more help.
