SOCIAL MEDIA MARKETER WANTED -- 3

I am looking for someone who has a strong social media presence, meaning he/she is on a lot of social media groups , ie if he/she posts an image or video a lot of people will see it instantly. This is for spreading the word/creating awareness about new apps. I am not interested in paid advertising on social media, ROI is ok for big ticket items, but small items such as an app it is more tricky. If you can provide results (ie traffic) and you know what you are doing, I would like to work long term with you. I have several apps that i work with, in a wide variety of niches. You have to be based in a western country for sure for obvious reasons, preferably US/CAN/EU. I will pay $25 for posting an image + video on 25 active groups or such as is pertinent to the app, so if it is a kindergarten app dont post it on a fashion group , etc. meaning use good sense. Please let me know if you are interested. My budget is limited because these apps are new business ventures, but that can change with your help. Please remember that the primary target customer group is in North America. BUDGET $25
