I recently took on a project to build a webpage. I am an experienced developer but never worked with coding a psd file into a webpage.

Now, the psd file uses a specific font, which I do not have probably, as I can see it in grey and [ ] at the bottom of the fonts list.

Sorry for the naive question, but what am I supposed to do from the client's point of view? Should I have that font? Should I buy it? Can I extract it from the psd file? And then, does it come into the web-page as @font-face?

Thanks for any suggestion
