Sew edges of 30-35 gym towels

Hi there, We need 30-35 gym towel edges stitched in a very professional tidy way, they are for retail. See attached photos. I have been told that we need an upholstery machine to do get this stitch - although the towels are very light and thin. Please only apply if you can do a very clean stitch - like the white edge stitch on the blue fabric swatch - photo attached. We assume you are able to do a very clean, straight, professional stitch around the towel and add our care tag into the stitch neatly. We have around 30 gym towels, size of the towels are approx 37 x 90cm. If you are in Sydney that would be great. Half towels need white stitching, other half black. Thank you and kindest,
