Have acquired InsuranceComparison.com

I acquired the domain, InsuranceComparison.com recently and it took me nearly one month to close this deal. I have sold a few insurance domains and I like that niche.

I am planning to develop this domain, InsuranceComparison.com into a business website but it would need extensive project to do such a website, I believe. Do you recommend/know any business website developer who could create an insurance comparison website?

I am thinking of using subdomains such as

Car.InsuranceComparison.com, Health.InsuranceComparison.com, Pet.InsuranceComparison.com
Home.InsuranceComparison.com
Travel.InsuranceComparison.com
Life.InsuranceComparison.com

etc…

What do you think of such subdomain creation? Would you suggest creating directories instead of subdomains?
