Looking for a body shop that will mold a lip for me..

from this..



to this..



I went to Pirellos off Plfumm and they told me they couldnt/woundn't do it. Im guessing because it was something they couldn't gurantee?
So now I'm looking for a spot that will do it..I know the consequences of molding fiberglass (possibility of cracking down the road) but would still like to have it done..

Thoughts?
