Wordpress Multiple Languages? Charge?

The lady I'm doing an e-commerce site for wants her site to be bilingual (multiple languages). I found a plugin for it, it looks pretty cool.


Does anyone know of a better plugin or how much I should charge her for this while it's $79?

Thanks guys, I really appreciate your help and input you've gave me thus far.

Don't nickle and dime your clients. I would charge her cost + a small installation fee.

Thank you! I appreciate your input. The only reason I feel I should charge is I gave her a great deal on an ecommerce site. For $300
