Debug Website Errors

Feelancer will need to fix website errors/bugs I've found on my site. My requirements are as follows and here is the link to my website www.onethroneapparel.com. Create coding where I can dictate what size a t-shirt is available in. Right now the default settings automatically show xs,s,m,l,xl,xxl when I sell out of a size I need to be able to remove that size independently. Shipping formula - we are currently offering free shipping on our website - however there is a formula that overides my free shipping and when a customer selects 3 items or more the shipping automatically calculates. I need this fixed! I need a coupon code formula so I can offer coupons to my customers. add our hours of operation on the home page instead of roll over to zoom on my picture products please change the wording to double click to zoom. fix the product ordering formula... on the men/women and kids page/ items should appear in the ordering I select from the admin panel. (except on the home page - those items are ordered by the newest to the oldest) Fix the number of boxes that show on the admin panel for number of different style or color an item is available in. There is a defect there because sometimes when I upload a photo a Khalla bear will pull up and post to the product box. Or sometimes when I select a certain product to post and click ok an entirely DIFFERENT product will show. There is clearly an error in the coding. (I will explain in more detail once project is awarded) build a new tab for jewelry/accessories section on the website We would also like to discuss what it would take to add music to our website and if this can be done.
