which supplier did you find that does the design of the ibeam as well ?

I have a 7 M span

I got some names from a glulam beam trade assoc - don't have it to
hand (did a web search). Sent 3 of them my requirements last week but
haven't heard anything yet. In the mean time I've found a local
structural eng. who is doing the beam calc. for £40. With his info I can
then directly get sizes for metal or wood.
