Hi, I have the experience required to finish your project successfully.
Things I will do:
Upgrade your store to Prestashop 1.7
Configure the default theme to show your products on the homepage.
If you have a custom theme, or custom extensions, they won't work on 1.7, so I will disable them. I will upgrade any prestashop extension, but not custom ones. If you are fine with that, please send me a message.
have a nice day.
