Annap-Originally I thought you said that the clients would lease the equipment from you and take it home with them. But since you would be in control of the equipment at your shop I don't think it would become "shambles"On the other hand, if there was a question of piracy you would have greater complicity if the copying was done in your place of business.
I don't know where you live, but frankly I don't think the copyright-holders would bother you in your operation...they are after bigger fish (figuratively)
