We need to have help setting up magento 1.8.1 Part 1: We need to be able to have one shop covering multible sites 10-15. On stocklevel we need to show stocklevel (on stock, expected on stock [date], out of stock) on 10-15 sites, so customers either can choose pickup from a store with product on stock, or wait for internal transport to the wanted location. Stocklevel needed to be imported serveral times a day. Part 2: We need to be able to import products, categories, description from an other system. File will be provide in what ever format is needed. Special specs: Pictures: Pictures will in most case contain an external link to an external webpage - in case no Picture is present, a cooming soon Picture should appear. In these cases we need information that a Picture is needed. Overrule: In case a single field has been changed, the import should NOT overrule the product/category, unless specially marked. We need a time estimate on part 1 and 2 excluding extensions. There are many more demands, but depending on the solution of part 1 and 2, the other specs will be released to the right person.
