For onsite training, typically the standard Rhino Level I and II training courses are each scheduled for three days. What I've found is that, at least for small groups, two days is quite adequate, so that's less time off work for you or your employees. Level III training can also be squeezed into two days, though it's a matter of focusing on your needs, three would be recommended. Contact me for more info.
I can also offer customized training, consulting, and help to get work done on your specific projects.
