Your link will soon be taken down, as FBF rules are that people are a member for a month before a site audit... but in the mean time...
It doesn't matter how your website looks, the question is how does your website perform...so how many enquires do you currently get per week by email / phone, where those enquires have come SOLELY from the website and not by any other marketing means?
The next question is, are you happy with that level of return? This will dictate what kind of feedback you need...there's no point getting feedback things you don't need.
