replacement of 3 window sills

I need a contractor to replace 3 x window sills (eg all 4 sides on 3 windows).

these are metal heritage windows so timber etc will be old.

I have the trim for these (eg the new front pieces that attaches to the sill and sheetrock but need someone to quote on replacing the frame/sill).

Would need someone who knows what they are doing so the windows dont get broken.

Cheers,
Dean
