looking for a BIG die cast Optimus Prime figure from the transformers movie?

I've seen some small ones that look a bit crappy. any idea of a website that does decent looking die cast's that are like bigger then 30cm?

Unfortunately, the only good Primes are 12 inch, at tallest. Due to toy safety regulations, nobody makes Transformers that big anymore, so you'll have a hard time finding one. Nevertheless, if you are okay with 12 inch/30 cm, here are a few recommendations.
If you want the metallic look, it's not going to be cheap. I'd recommend the Buster Optimus Prime, which you'll have to import from Japan.
Otherwise, Hasbro's pure-plastic Optimus Prime is also not too bad, and a lot cheaper. If you watch the video review below, there are comparisons between both, for you to make up your mind.
