There probably is a contractual issue with doing this, and it will be expensive anyway and probably get you a acetate (dub plate) which will only last 50 or so plays and doesn’t sound as good…(someone like Biotech or Raj will be able to explain better the reasons behind the quality loss, but Mp3 is a sub optimal format and then you will be converting it back to analogue and then re-cutting it to vinyl)

I suspect these days you are beter off making it into CD audio and using a CDJ, you can do that for the cost of the blank media with any computer, and there are less conversion stages involved.

tracks on vinyl are expensive because vinyl is becoming increasingly expensive to produce.

as much as I love vinyl/analogue technology (especially being of the agegroup where most of my early exposure to music was via analogue recordings) – I think market forces are going to kick in hard as a recessions coming and the commercial dance music scene is contracting, and more and more genres will move to CD / digital distribution. Already pystrance, UK hardcore and hardcore breaks seem to increasingly have gone that way..
