My customer, a translations business owner, just told me that he has been reading about Ruby on Rails and told me that "there are more PHP guys around there" and "it seems the community prefers it". What would you, as software engineer and freelancer, say to the customer to achieve these goals:

• Sell
• Make him see that the technology is my expert decision and Rails is as good or better than PHP (+ whatever framework) for this particular project.

UPDATE: Thank you all for the suggestions! Tomorrow I've got another meeting with him, let's see how it goes, I will update again :)

UPDATE 2: Finally I told him to read this thread and the result has been fantastic: He gave me the project and we are going to start right now. Thank you all for the help, you have free beer in my charge if we see someday :)

BTW: I learned the lesson: be as transparent as possible, because if you believe in yourself and your work, there is no question compromising enough to beat you.
