(It doesn't run right now, no starter motor, exhaust or rear brakes.) I used a mobile welder, who was cheaper (due to not having a workshop, etc) and recommended by a mate. He was happy to fabricate the panels needed from sheet metal, but if you were going down this route there are panels now readily available. These are a couple of suggestions: This was perfect for me, as it meant I could fix other bits while he wasn't there. 
£250 so far for some extensive work to the rear of both sills including new metal up to the top of the body kit, new seams at the jacking points, and a plate on the underside at the front of one side...(1) get it through the MOT - only needs to be sound within a certain distance (someone will know this... 
) of suspension mounting points and a few other key bits. this can be done with little concern for appearance and is probably quite cheap...(2) if you want prettty too, you get into respraying into the existing panels to blend the colour, and can start to get quite expensive.£1200 for rear arches, sill returns and rear lower corners to be fitted along with some repair work on the inner wings and rear panel under the bumper.£250 for all 6 panels I think.
