I seriously don't understand why people get so upset over grammar it just doesn't make sence haha
Grammar and spelling in a post are one thing, but your website is how you are going to be judged by prospective divers. Would you accept a resume that had glaring grammatical errors? I wouldn't as it shows a lack of professionalism, I want to see a professional website, sure you can how some personal touches come in but your site is way over the top. Not only that but a lack of bios is always concerning to me when dealing with personal service industries.
Now I compare that to TDL's website, a company which I have no affiliation with, the site for the dive is very professional. It tells me the price, what I will be provided by TDL, and very clearly tells me what is expected of me as a diver. I look at the bios and I can see their experience levels and who they are.
If I were looking today I would book with TDL. But perhaps you two are just going after different audiences, as I don't think TDL is looking to attract recreational divers, they seem to be still targeting technical divers.
