Build an Online Store

Things to be done in 2 days time for our magento store [login to view URL]: (some points are being more clear with images which you can find included) - we have issues with confirmation emails. It's not being send automaticly. I guess it has to do with the configurations of CronJobs. - At the product pages at the availabilty of the product we want to included some extra text from an attribute. For example: In stock will be delivered by the end of next month. OR In stock. Will be delivered on the 20th October. OR In stock. You have untill 14:00 to get it delivered by tomorrow! (see image) - At product level I would like the Description, Especification, review, etc.... tabs as what mediamarkt is using. See this link [login to view URL] They have all the tabs already open in the page and when you click on a different tab you will be directed there instead of that it is opening at that moment. (see image) - At product page level I would like to have also youtube video possibility and not only images. And for example when there is a standing image that the tumbnails are not in front of that image but just below. See this link for what I mean. - I want the cart and checkout page on one page instead of two separated pages. - When some products are added to the cart I want to have automaticly an other product added to the cart. As a present or as a promotion - I would like to have filters like price, color, model, etc. horizontally instead of vertical. (see image added for visual explanation) - make the website much faster Design and style must be the same as now and it must work for mobile views too.
