I'm a part of a team consisting of 2 people and between us we have handled social media marketing for our college fest. You can have a look at the page 'Sympulse' on facebook. I also handled a digital media marketing project for ACC Limited India.
My skills include english writing, so you wouldn't have to worry about the quality of your posts either.
If you need any other details, you can browse through my profile or send me a message.
