In my country, Romania, it's around 80 EUR for the sills brand new and another 250 EUR for professional shop to cut/weld/install/paint. I had them done on my TDI, now I need to do the same thing on the ED30
+ front fenders, hood, front bumper with new lip. Gonna be quite a bill.
Having the whole car resprayed by them with the sills and everything done would cost me ~1450 EUR but I think I'm just gonna do the front end as the rest is pretty clean. These are "friend" prices btw, other garages charge way more, as a random walkin.
