I'm very unsure about that site logo. It doesn't work for me.
Reason being that its not very print friendly (I don't know what direction you'll be going). I also think the brown background doesn't work with it. I'd prefer the green on just a white bg.
If I was you though I'd seriously consider another typeface and something non-italic.
Perhaps even consider having black text for your logo, with a green symbol, or something green around it for the (Irish green / relationship).
The images in your product catalogues are very large (compressed with HTML) which means very slow load times for those on a slower connection. There are several image libraries in PHP that can help with this.
All your pages titles are the same which is not good for
SEO.
Other than that I think it looks ok.
Sorry if it comes off a bit rough (can be hard to read true intentions over a forum), but just wanted to be honest.
