String art machine

I am looking for a freelancer who can design and build a string art machine that can create custom images up to 16×20 inches in size. The ideal frame material for the machine would be plastic. The machine should be able to create string art designs that are based on custom images. The ideal candidate for this job should have experience in designing and building automated machines, and should be skilled in working with plastic materials. In addition, the candidate should have a strong understanding of string art techniques and be able to create designs that are aesthetically pleasing and technically accurate.
