I am exploring the feasability of a business offering seal engraving (family crest / coat of arms etc) on gold signet rings.

If someone can answer a few quick questions I'd be very grateful.

Any suggestions for the type of machine? Recommendations for machine manufacturer? Rough cost of machine.

I intend to employ freelance designers to turn a picture of a design into a format that will tell the laser what to cut. Any suggestions for best program with plenty of available freelancers capable of doing the job. What should I budget for this.

I'm based in the UK and grateful for any advice.

Many thanks.
