PRINTS?

[pixypop.livejournal.com]

I know this isnt really crfty but I am thinking of selling my digital and traditional artworks as prints. To be perfectly honest I have no idea where to start i have been viewing many peoples art and there prints and many people use Glicee Prints but the prices are so absurdly expensive and I am getting so confused with all the ratios, When my image is at 1000px it ruins the whole picture.
Anyway so does anyone have any tips on what to do and what sites to get them printed at (preferably Uk based sites which have a wide range of paper variety!).
