Add products to my e-commerce store (Prestashop)

I have a few websites that I am trying to put together but now I need help with adding products along with full description, price, size and pictures to the store. I could use some help with a bit of customizing if you are knowledgeable about that as well. You can choose to do the data entry to add the products or help with site customization or both. As well, please note that the items will need to be taken from various websites and you will need to add a prefix in front of all products so I know which supplier I am getting them from. Again, you will have to download images, description and pictures from a few other websites. I need someone to start immediately and you will need to add categories and subcategories for the products. Thank you and happy bidding. Budget for the task is $3-5 per hour or $60 total
