I am looking for suggestions on a startup operation . I am looking for rough cost estimates for equipment materials things like glove boxes better yet flow hoods mini clean rooms and grow rooms . I am handy with tools and will build stuff if it is cheaper. I am looking to start small but be able to produce some profit to eventually grow. If any body can remember what some of these materials have cost them and will share I would appreciate it . Thank you. Also any links to hepa filter vendors?
