I've used BigBlueSaw as well as some local makerspaces for my waterjet and lasercut needs in the past, and I've been happy with their services. Where does your business fit within that marketplace? Is your advantage pure cost (which I'm impressed with by the way, a $12 shipped part is ridiculous)
Seems like they have much smaller limits on part size compared to big blue saw. Seems like they are mostly targetting hobbyist/art stuff. 300mmx300mm is too large a limitation for bulk work.
I used BigBlueSaw for making frames and parts for some robots I built for fun. They fill a nice gap in that they serve hobbyists but can work with materials and sizes that support beefy, industrial style designs. Conventional machine shops won't give me the time of day due to small quantities and non-recurring orders.
Anyhow, I went home last night and knocked together a little cutting template for some hobby leatherworking I do. At $30 CAD shipped, it's hard to resist trying it out. If I'm happy with the result I'll share the site and template on some leatherworking forums - those guys are always looking for easy ways to build templates. Good luck with your launch.
