WooCommerce Discount Setup & Image Placement

I have an ecommerce site created in wordpress. I need 2 small png files placed in the homepage that announce our end of year sale. And another png file placed in our SALE page that says that the items in that page are not on sale. I will also need the site to be set up to apply a 10% discount at checkout. This will be a 5 day sale and will start on 1/27 at 12:01AM and end on 12/31 (midnight) So the three PNG files need to be removed and the site needs to be restored to its origin without a 10% at checkout. I will provide the 3 PNG files needed.

Ideal skills and experience for the job:
- Proficiency in WordPress and WooCommerce
- Experience in implementing discount functionalities
- Ability to place and design images on a website
- Understanding of eCommerce sales strategies.
