Private English Tutor Needed

I have a student who I can not continue with, He is looking for private English classes. He works in Human Resources and Recruitment and would like to have classes that reinforce his general English but also focus on business contexts. I am looking around to be able to recommend a private tutor to him. Any information you can give would be very welcome. I know I am also an English teacher and you may not want to provide commercial info and I will, of course, understand that. But I do need to connect him to a quality tutor as soon as I can.
