Magneto Website Build

I need work on is a Magento website, I currently have a theme for it but I needs some custom work done to it. Currently, I have the theme installed and is active on my test server you can view the website here http://dev.crazyplasticssa.co.za/ and the theme here https://www.portotheme.com/magento2/porto/demo1_en/. A feature that I need to be implemented on this website is for products to not display their price for now as I will not actively be selling anything ill only start selling products later, when I do start selling ill need the prices to be displayed, the only tricky thing is that for now ill be uploading products manually then later ill be using a third party software called DOLFIN to push the products to the website, please let me know if you will have any issue executing this? The first change needs to be made to the homepage, the page needs to look like the mockup image I have attached here. Please let me know if you will have any issues with getting it to look like this with the current theme. From here the development for the inner pages can start but for that, I would prefer to have a call with you and your team as the changes will need to be referenced on the live website and other websites. Please can you provide a timeline as to how long you will need for the first 2 changes to this website?
