I’m sorry, but it would take more than 10-15 minutes to go page by page through your content and find all the grammatical errors. Like @John_Betong suggested, grammarly would help.
Just copying the first paragraph into Grammarly provided five easily fixable errors. I guarantee if you copy/paste the rest of your content into a document, it would find more…
They are clickable links, but it just returns you to the top of the page. I would agree that you should remove the href from around the image since it makes no sense.
I could be wrong, but I get the impression you’ve bit off more than you can chew. I would suggest you swallow, take a break, and develop some basic communication skills. Web sites are a form of human communication. If you want a computer to build your site you’re not going to get many humans to visit. If you can’t spell, get a dictionary. If grammar is not you strong suite, get a College Harbrace book. You’ve got to put in the work, there’s no app to do it. If necessary hire a content writer who’s trained and endowed with the skills necessary.
Just my opinion.
