Install & customise marketplace using Saleor platform (Django/open-source/developer-first/headless)

Hey there! We run a stock video marketplace called VideoPlasty: [login to view URL] It's a pretty standard marketplace with digital downloads, video previews, etc. It currently uses WooCommerce which was good when we started and didn't have any money, but we now need a custom solution for the future and for scale, optimized and built around what we do. We want to use Django for that and because the budget is not that big, we want to use an existing open-source platform as a foundation and customize it, rather than build the entire platform from scratch. We want to use Saleor - [login to view URL] (check out their demo too) It's built on Django, open-source, developer-first, headless, so it's exactly what we need. There's no need to reinvent the wheel, just customize it. Here's a document with all the required customizations, split into two phases based on priority. Depending on cost and estimates, we will start with the first ones and potentially delay the second phase for next month or so to balance funds. [login to view URL] The 3 most important front-end pages are designed and included there to get an idea about the general UI/UX. It's important for us that this marketplace is optimized for speed. Also optimized for SEO, but I see that's already included in Saleor. In the near future, we will upgrade it to a multivendor marketplace, so please keep all those things in mind. We're looking to build a solid, long-term relationship with a developer or team, as we want to keep implementing new features all the time. For now, we want a solid and functional v1. Look forward to hearing from you! - Eduard
