3D sub surface laser engraving machine

I am interested in purchasing a compact 3D sub surface laser engraving machine to open up a small business in a shopping center. (weight no more than 150 kg). I locate in the USA.

Engravement size no less than 65x65x40mm

My business will be in a shopping mall cart. I would be interested to hear what machine model you would recommend for my business idea.

I would be interested in getting more information about the cost, shipping and the time it will take for it to arrive in the USA.

My budget is within $20000

Thank you so much for your time. I hope to be doing business with you.
