No worries, I bought mine from THQ for £600 (fixings included) and a local body shop painted it for £200.
Fitting is straight forward but you will need an extra pair of hands to help support it during installation. Also make sure the foam strips and adhesive are the very top edge of the splitter. The adhesive will squeeze out where it meets the bumper so be ready with white spirits and cloths. Also the instructions recommend an 8mm drill bit for making the 4 scrivet holes in the bumper. This seemed way too big so I used a 6. When I fixed the brackets to the splitter (step 1) I also frog taped them in place to make it easier to line up later down the line.
