I need an e-commerce (Opencart, abante etc) website upgrade.

I am looking at upgrading my current opencart website including theme and capabilities. I would like to upgrade our current theme to a Journal 3 theme and then I need the website to have the following capabilities: 1) Normal e-commerce capabilities including categories, sub-categories and products 2) One-page checkout with guest checkout functionality 3) Ability to build/ customize a product based on pre-populated choices. Eg we sell microscopes and I want the client to be able to essentially build their own microscopes by selecting certain specifications. The price of the product and the product image must change based on the client's selection. 4) Blog 5) Section to post upcoming events/webinars as well as post previous webinars and videos. The ability for customers to register for these events. 6) Forum 7) Option to be able to rent out select products with pricing based on the duration of renting out the product. The client can choose which dates to rent out the product through the website. 8) The ability to create custom forms and have them displayed on the website next to the categories or independently. 9) Able to import/export products 10) Friendly back-end customization 11) The option to replace the price of products to text. Eg instead of price showing it will say Request Quote etc. 12) PDF download in product description 13) Ability to upload products to google merchant center automatically. 14) Ability to upload products to social media 15) Predictive search 16) Upload videos to product description 17) Integrated order tracking (we use The Courier Guy) 18) Mobile friendly site. 19) Able to compare products 20) Auto-complete client address 21) Abandoned cart module 22) I have bought the following extensions for my current website: Call for Price with enabled / disabled Add to Cart button Form Builder Pro Import/Export PRO - The most complete importer for Opencart Add Unlimited Product Description Files-Pro If you are able to provide the above options with a different open source e-commerce platform then we can also explore that option as well.. Optional extra- if possible a website scraping tool to allow for faster product upload ( details can be discussed if this is possible). This is for my own benefit and does not relate to the above requirements.
