From the Lancair web site (FAQ's) http://www.lancair.com/Main/faq.html

How long does it take to build a Lancair airframe?
It takes about: 700-1000 hours to build the Legacy, 500 hours to build
the Legacy FG, 1300-1500 hours to build the Lancair ES, 1300-1500 hours
to build the Lancair IV and 1500-1700 hours to build the Lancair
IV-P/Propjet/Sentry. These hours do not include firewall forward
installation, electrical, paint or upholstery.

    In reality anything under 5000 hours for a IV-P is a "rush job".
    

Can I get builder assistance?
Yes. Lancair offers a builder assist program for all our aircraft. This
program varies for each model. The customer spends 1, 2 or up to 10
weeks with us and will start building their own Lancair. We offer
technical assistance and guidance during this build time. We expect to
see customers finish their Lancair Legacy Fixed Gear in as little as 10
weeks.  The Lancair ES/ES-P/IV/IV-P/Propjet in 26 weeks or less.  The
cost for the builder assist program is $4,000.00 per week.

    26 weeks or less??  I wonder why it took us over 5 years then ?

Lancair could do themselves a favour by telling the truth to potential
customers. Caveat Emptor.
