Why you don't use sound or subtitles in video

Dear Gents and Ladies. My customer company( for financial and marketing advice) has a huge engineering firm in Harar-Ethiopia. We have already installed a big embossing machine, a ray cutter bed-machine, benders, and a variety of laze machines. At present we're on producing embossed doors/ windows, all furniture from sheet metal and render services of manufacturing vehicle motor parts and others. But we're not that satisfied as we we're thinking about specializing. Producing enclosures and edges of CPUs and electronics appliances might be one good endeavor. So, can any of you help us in forwarding some companies address which would be supplied with such products? Thank you very much.
