I contacted Photobox about this after getting some poor colours on a christmas present.
I spoke with their quality control manager who sent me the Fuji paper profiles for Glossy and Matt prints that they do in the following sizes on their Polielettronica machines:
10x7" A4 12x10" 15x10" 12x12" 14x11" 20x8"
A3 16x12" 18x12" 20x16" A2 30x20".

GLOSSY
Instructions for photoshop:
You'll effectively be soft proofing your images and you can do this in
the following way;
First install the profiles on Photoshop. Then, before uploading your
images, convert them to the profile and make any required adjustments
before saving the new version of the image (save with or without the
profile):
1) Open the image in Photoshop and discard any other profile in the
image if it has one.
2) Go to View / Proof SetUp / Custom
3) From the drop-down list select the Fuji paper profile.
4) Select 'preserve colour numbers' (this will show the image as it is
presently printed)
5) Make the required adjustments so that the on-screen image appears
as you want it printed.
6) Save this new version of the image and upload it for printing.
Once these new versions have uploaded, the prints from them will be a
close match to what you see on-screen.
NOTE: When you look at your images in another photo program they will appear over saturated.
Hope that of some use folks!
/edit - the re-prints came out a million times better!
