Wordpress expert wanted for few tasks

Hi, Our client's website is [login to view URL] We have the following tasks for now: 1. Please take a look at all of my H1, H2, H3 headers. They are not right and messed up. Eg: [login to view URL] <h1> Headings Status Your page contains H1 headings. Their contents are listed below: Clear Book Bags – Large <h2> Headings Status Your page contains H2 headings. Their contents are listed below: Need help? 314-517-2024 The Leading Authority in Clear Book Bags Video Photos Related Products It does look like the H1 is showing up on the Title 2. On the link [login to view URL] need to add categories on the left tree under Wholesale. I would like to keep all items on one page but still add the new categories. The new categories would have the existing listing and same text for each product. If that is creating duplicate content then maybe you would not recommend that. Do you think that having separate categories (wholesale clear backpacks, wholesale clear tote bags, etc.) for each will help w/ ranking them much better? Following categories need to be added: Wholesale clear backpacks Wholesale clear lunch bags wholesale clear tote bags Wholesale Clear Shoulder Bags Wholesale Laptop Bags Wholesale Clear Gym Duffle Bags Once these tasks are completed and client is satisfied we have much more work. We are looking for a long term business relationship.
