Magneto Site modifications

Hi, I am looking for a Magento EXPERT. The person should have excellent knowledge in Cloud Linux hosting also. I need few works to be done on my site. My site is hosted in the Linux private cloud. Magento version 2.1 1. There are more than 5000 products on my site, but it is not linked to any of the categories in the homepage. It needs to be linked. I.e. In the home page menu there is a menu item " Electronics" but no items in the uploaded products in the electronics category are linked to it. It's a simple work of course. ( If someone volunteers to do it in 4 hours, the project is yours) 2. I need 4 different user logins, meaning, User type one: Common users - They should see a different price User type 2: Whole Sellers: They should see a price different from that of Common users Similarly, need User type 3 and 4. all these users need to have a different pricing. ( This is, of course, a basic work, as we need to set user roles in the admin panel ) My site is DEAD SLOW, so if possible, I would recommend fixing it. the URL is: [login to view URL] I want who will respond to me promptly, via chat or messengers. Whatever you bid will be the budget, do not negotiate after you bid. If you can start immediately, then please bid. Tell me in your bid that you can start immediately.
