Someone wants to buy my photos

[Moose.]

I've been approached by a company who have seen some of the photos on my blog and have asked me for some further photos so they can select some to purchase (for what, I don't know yet). So far any time anyone's ever asked to use my photos on their blog/website/whatever I've just said no worries, just credit me for them with a link, however those have all been personal requests from individuals for non-commercial use.

This is the fist time a company has contacted me and also offered up front to purchase from me. I have absolutely no idea what to charge as I'm by no means a professional photographer, so was curious what would be a standard going rate?

Thanks for that chaps, I'll see if they come up with an offer first and take it from there
