Looking for somebody that can help generate/drive sales for my Stock Audio Profile

I hope this is the right category. I'm looking for someone that can generate/drive more sales for my companies Stock Audio Profile on [login to view URL]: [login to view URL] The portfoilio hosts high quality audio and soundeffects which were used by notable companies such as Disney, Marvel, Warner Bros., Blizzard, Chevrolet and others. However, as the marketplace got bigger, it became harder to be seen or in this case heard, which resulted in less sales over time. I'm well aware that sales can't be guaranteed, as the audio has to appeal to the customer and his project. However, a noticable increase of sales should at least become apparent within a month. Please feel free to ask any questions with regards to details about this kind of job. I'd be happy to answer them, so that both sides have a clear understanding of the requirements. Kind regards, Matt
