Online store for digital downloads (or maybe streaming with S3Media?)

We are selling digital files such as video courses in .mp4 format and our printable art in .jpg format (kompressed into .zip). We need expertice in Wordpress. We would like to sell our digital files for download, but we also would like to know if there is someone out there who have created web sites with streaming services using plugins like "S3Media Stream" and the membership plugin "MemberPress". We belive streaming is the future, so we want to look into it also. We are seeking that expertice but that is not a must - the most important thing is the digital download store. The reason why we want designers that have experience with Wordpress is because we tried creating it ourselves in Wordpress and found it could actually work! The only problem is that we were not able to get it right, we got bugs so we gave up. But this means we kind of know what we want and have tried some plugins - plus we have some licenses for them already. We have sketched the design and some of the futures for the website in Pixelmator (Mac app that is similar to Photoshop) - so we can easier express what we want and maybe easier get expertice and advice. We would need these pages: Header menu 1. Home: We have sketched the design in Pixelmator, We can send that to you by email. The home page would need sliders and lightbox futures (video pop-up) (We have a license for the "MetaSlider" plugin). 2. About Just normal text and pictures for now. We may add a video later. 3. Galleries We have sketches of how we would like them to look - and we believe the "Envira Gallery" plugin would have the futures we would want). 4. Store - WooCommerce or plugin for digital downloads (There is a digital download future mentioned to be within the "S3Media Stream" plugin but we don't know if and how that works). - PayPal setup. - Terms of use lightbox/pop-up. - Cart in the header menu. - Add to cart pop-up future (We have tried "WooCommerce WooCart Popup Lite" plugin) - Login / My account option in the header menu. - No quantity future. - Future to add taxes for norwegian costumers BEFORE PayPal (where the store is). - Search bar on the top of the menu. - Newsletter future (haven't tried any plugins). - Other costumers also bought... (future within woocommerce) - Recently viewed products (future witin woocommerce) Footer menu 1. FAQ As clean as possible. Maybe just a dropdown future. Have looked into the Ultimate FAQ plugin. Looks like its got what we want but we haven't tested it. 2. Terms of condition Mostly a plain text page. 3. Contact us Contact form with "locked" subject option - and max 1000 characters (Contact form 7 plugin). P.S. We have domain and hosting at one.com.
