Looking for sample handbag machinists or manufacturer UK or abroad

I am in the process of designing a new handbag brand and would like to source a machinist for initial samples here in the U.K. Base is to be decided but will either be PU or Leather- all hardware and materials will be provided. OR I would be interested to hear from accessory manufacturers who can provide a service from initial samples through to delivery of a product. I am very much in a research stage but looking to begin discussions with experienced people who may be able to offer the above services. Thank you!
