Here is one tip that can help you run your business better potentially:
I recently was dealing with a potential client who spoke Spanish but not much English. She could understand me but speaking for her was difficult. I told her not to worry and I would email her all the information she needed to be set up for a merchant account. I then went ahead and wrote my whole email into Google translate and it spit out a translation which I then emailed to my client. She must have liked the Spanish email, because she sent in her application without question. The translations available are quite extensive and I believe you'll find this web site to be a very useful tool.
