IMO If you can’t have a good website, don’t have one. If you can have a good website its a useful tool. When someone hands me a business card, I’m going to want to do a bit of research before I agree to a meeting in which they are going to try and sell me something.
Once your new venture is in any way established, a potential client googleing you (other search engines are available apparently)will find info on your business. It might as well be info you have put there for them to find and it needs to explain your company both in what’s said and in the quality/attention to detail etc.
A company with a crap website will not get a meeting to pitch their goods/services, a company with no website might.
