It's a hefty old site with good information. It's not obvious whether they are a broker and will search for quotes or are reps for one company (so I guess likely). The quote form gets contact details only which is all you need. Long forms reduce uptake. I would personally make it even shorter but tracked from it's source for stats. It's more work for the Rep qualifying wise but will yield more leads.
Probably couldn't get more targeted than a banner advert on here.
