I offer iGaming content in English and Finnish, and do so with the price tag of 5 cents per word. I know the whole niche quite well, though for football and tennis tips you might consider hiring someone else. On the other hand reviewing betting sites or writing about eSports is right up my alley. Same goes for slots, casino and producer reviews, newspieces, strategy guides, random articles and industry news. I have a background working in online casinos, and have knowledge and understanding of the whole system from customer support to affiliates, banking and whatnot. On top of this I have worked in IT, which means SEO is quite familiar to me. Contact via PM or post in this thread if you could do with some quality content.
