Water Jet Cutting
Marzee Water Jet Services

If your part is made of flat material, send Marzee a DXF line drawing with only one dimension for import scale-check, and they will supply the material and cut the part to shape for little more than the cost of the material.  If you are outside the Phoenix Metro area, send them your address and ask for a quote including shipping charges.  They will supply a quote by email, and then you can call them with your credit card information and authorize the job.  They will cut your part and ship it to you.  Great Service.  Good people.  Go To Marzee website.
