Functionality, especially with interactive features, is the single most important element of a professionally done site. At this point, I don't think the look of your logo is your most important consideration.
Engaging your potential clients by providing them with working interactive capabilities is essential. Your Free Quote page,

My personal preference is to never have mailto links anywhere on a site. The two strongest reasons are that
1) address-harvesting spiders are working sites to find valid POP boxes for their nefarious
aggregate-and-disseminate purposes, and
2) even unsophisticated Web surfers don't hold in very high regard having their resident email client load as a means of contacting any site, let alone a purported Web-specialist's. If I seem harsh, keep in mind how demanding a client can be; how p.i.s.s.y, how irrational they often tend to appear. And they're supposedly paying you, while I'm being p.i.s.s.y quite without remuneration.
Good luck to you. There's a lot to learn and it's an extremely tough arena you've entered, but before all things: enjoy what you do.
