I need an expert who can solve my shipping problems. I currently have flat rates set up for three different zones (Ireland, UK & Rest of EU). I need the shipping set up so that Ireland receives a flat rate of €5 (this is how it is currently set up) but the other zones are charged per weight. So that if someone buys a very small item they are charged accordingly. But if someone buys a large item then they are charged a greater shipping charge.

I only want someone who can do this job very quickly and precisely.
