I won't choose a company based on their website, but I will eliminate one based on their website. (Let me preface this by saying that my website is currently down, and I have someone working on it. Don't want to sound hypocritical!) My website isn't the main way I first attract new customers, but they do check out my website before contacting me (which is why I hate that mine is down right now; I just sent out a proposal I'm really excited about).

For me, a sloppy website suggests that the work performed might be sloppy, too. While your home page initially looks great, once you explore a little bit, you see text that overlaps pictures as well as a few grammatical errors. I think that tidying up your website would help potential customers feel you'd show the same level of detail in the services you provide.
