You should try advertising the job into an European job site ....and explain the skills you are looking for in details ..and also ..ask for experience ..and a portfolio with actual products..and other previous work ..to prove the skills and work experience...I will link here a few sites that will be appropriate for that ..
Another idea is to contact the technical college and faculties and the design ones too..and advertise directly there ..or try to advertise an actual tournament with the best idea winning the job...and advertise it into Best Jobs..or European Jobs..site ..

keep in mind that sometimes the best for the job might not afford to be present on a interview..or so....for material difficulties..It happens..after all its art world..:D if I were you ..I will keep this in mind..and do things cheaper as possible for a person to present a candidature ....cause the best looking one ..or the first might not be the right ...but ...the poorest it just may be...
