The only problem is a new website doesn't have a track record, which would mean you'll be the first one or the first few. Because of that you're better off to work with companies that have a known track record. It's also good to give new websites a chance, because unless they get that chance there isn't any easy way they can demonstrate what they're capable of doing. Because of that, if they want new customers they've to offer something the other companies aren't offering, which will mean you'll get some advantage for trying their service. If they do a good job you can recommend them to others. So the question you'll ask is what do you get from this new website that you don't get from the others? Low price might be one attraction or if they've good testimonials and are genuine, they could be worth trying showing you it's difficult to make a decision. It could always end up being trial and error.
