I'm an BDE expert, with team web and APP developers, and a digital marketer with experience in every area you listed. I've Develop over 50 campaigns in app and web, helped small companies get first page google rankings for related keywords, and run Facebook campaigns that generated about 5,000 new page likes. You're passionate about education: I'm passionate about digital marketing. I'm sure I can help you achieve and hopefully exceed your goals!
Please note that while I'm new to upwork (I recently joined on a friend's recommendation) I have plenty of experience. I'm a native English speaker based out of india. I see that you're in other country - but because freelancing is my fulltime job, I am usually available at flexible times. I try my best to ensure that our communication will be as detailed and timely as possible.
It sounds like you have a lot of different needs for your project, so the first step would be to get on the phone (skype) and hammer out the details. I want to make sure I understand your product and your needs before we get started. It also seems like this has the potential to be a longer term relationship, so for those reasons, I haven't included a fixed quote. My hourly rate is $7/hr.
