Best place to get replacement panels for welding repairs

[kcsipler]

Bought my e30 a year ago and just beginning the big restoration work needed to make it road worthy

325i needs alot of restoration work. Both sills, inner and outer, are completely gone and need cut out and re-welded, floor pan is rotten, rear driver arch is gone, inner and outer also the battery box in the boot needs done.

Seen carbodypanels4u.co.uk supply everything I need at a reasonable price but unsure of quality Any suggestions on where to find these parts of high quality?

Been in contact with a welder and he requested me to buy parts for him to fit

Thanks in advance
