There are a few examples of mixing up your homophones (words like their and they're). Just get someone with fresh eyes to look through it. It's easy to skip over those sorts of things, especially if you've been working hard on getting the message right
Apart from that, and it's completely up to you as to whether you take any of these suggestions on board-
1. How Do You Become Vegetarian-
In this you recommend someone going to their doctor beforehand. If you're going to mention this, then I'd also mention that it might be wise to go to a doctor who is at least open to vegetarianism. Everyone has a bias (as you'd have learned studying journalism). Even doctors have a bias, they live in the same world we do and are subject to the same messages, like "But if you don't eat meat, where do you get your protein?!"
2. This is a general site thing, you don't really say where your business is based? I'm assuming it's America because you talk about Independence Day. I think being a bit clearer, on the site, about the locations you're catering to would be a great thing. It sounds like an awesome idea!
Please don't be disheartened by the points I've mentioned. As I said, this sounds like a great idea. It just requires a bit of tweaking. Good luck!
