Yes. You can write an invitation letter for your friend on the company's letterhead. The letter should clearly clearly state who you are, what services you are offering, and why you want to invite your friend to the training sessions. If there is any indication that your friend will be working in the US during his time here, such as organizing tutoring and training sessions, his application will most likely be denied.
