Verkaufen Sie etwas für mich (Selling something for me)

We need some help with selling something. We have a cosmetic shop in Germany and need a support to generate sales by using the right marketing tools. They should guarantee the best correlation between cost (as less as possible) and earning (as high as possible). The website is already online and the SEO process is ongoing. Before we start, I would like to know: - Why do you think, you are right person for this job. - What is the official language of Sweden - Have you ever done similar tasks before? - What will be your plan to be able to generate sales from the first two weeks on. - What would your monthly price for this project?
