Draw views of industrial filters for a staff training booklet

For a staff training booklet I require drawings of my company's industrial wastewater filters in various stages of dirt build-up. The drawings can either be done free hand or in Adobe Illustrator. Required are three simple drawings, each one based on the same base view. I have detailed instructions of what to draw and some photos of how dirt build-up looks like. I will provide high-resolution pdf files that show the filters in isometric view. You can base your drawings on these pdfs. Ideally, you have experience with engineering drafting and/or have previously illustrated industrial equipment. It is a requirement that you don't publish the completed drawings, e.g. in your portfolio. This is for reasons of intellectual property attached to the equipment. Please contact me if you are interested so that I can provide detailed instructions. Peter peter@[login to view URL]
