Stylesheet authoring clearing house

I'm having discussions with people about setting up an XSLT scripting clearing house. The basis being that organizations want people experienced in writing XSLT, and XSLT scriptwriters read these XSLT pages. As a basis it seems fine. As often the case, the devil is in the detail.

Does the hirer know what skills are needed? Is it XML input? Some other input with 'up transform' skills needed? What output format? What degree of difficulty? Will it need XSLT 1.0 or 2.0? Schema aware or not? Schematron or something else needed. It was pointed out that few agencies look for XSLT skills. It's usually one from a large number of listed buzzword skills.

Then the candidate. I know XSLT. OK. Like DC/MK? Like me? Like the web monkey who wrote 3 lines using the PI? Where in an infinite spectrum of skills do you fit? Not easy to judge over an IM chat, even a telcon. References? Maybe. Again not reliable. Word of mouth and recommendations seems the cautious route.

I'm tempted to hang out the hoarding and see if anyone sniffs.
