Dear Urban Village
Good day! I do market analytics on a professional level for few years already. Competitors analysis of this sort is easy and quick for me. From a review of your Comparison Chart, I think that few other aspects can be added for consideration. For example, add website traffic and rank (Alexa ranking).
Also, the fact that I've previously used some of these platforms will help me get around easier.
My educational and professional background is in marketing. Both bachelors and masters degrees are in marketing. Over 7 years working as a marketing professional, the scope of responsibilities includes market research, business planning, marketing plans and budgets, marketing campaigns and events.
Let me know if you're interested in a long-term part-time freelancer. In such case, I could forward my CV for your perusal. I am in Tasmania currently, but can travel to Sydney occassionally if required. If not, we can stick to one project at a time scheme.
Kind regards,
Maria
