Your typical bootcamp course takes 8-10 weeks. It's (hopefully) a carefully crafted experience that will get people to a standard where they can be useful within a fairly constrained setup e.g. build crud apps with rails. Given that you're not going to be able to provide this and that even if they did have a bootcamp available they wouldn't be available for a couple of months your task sounds impossible. If switching jobs isn't an option you need to work on expectations and push for alternative resourcing options.
