Receipt and Wordpress website and inventory updates

I am looking for someone to help with the creation of digital receipts and some WordPress website design and management. Specifically, I need someone to help with the creation of digital sales receipts and also create a WordPress website. Additionally, I would like for the individual to help with the daily inventory updates. The website should have eCommerce integration, blog capabilities, and a portfolio display. Lastly, I need someone to perform frequent inventory updates, preferably every 2 or 3 days. I have several websites with WordPress with over 5,000 to 10,000 products.
