Shopify Outdoor Store Product optimization

I have a small store that I am opening using Shopify. The layout is complete with minor changes from me as the products get correctly listed in the proper categories. I currently have just over 100 products. I need someone who is very good with the categorization of outdoor camping/hiking products. I have a store that I like I can share with you as an example "rei.com". I like the menu structure they use which is far better than mine. I would like to begin the project as soon as possible.
I will need a search function installed and advise on any additional add-ons I should install.
