Doing any kind of tasks wont be a problem, more especially if it will include tasks like dealing with customer concerns, billing, retention, sales, technical support and so forth. My experience includes Email Marketing, Lead generation, and leading a team of 30 for more than a year.
I'm also efficient as a freelancer / doing jobs at home since I've been doing homebased Jobs for more than a year now, and my previous task includes Lead Generation, Email / Social media marketing, Outbound appointment setting for an auto insurance. I've been working with minimal to no supervision since reporting is done every other end of shift. My client will just contact me if there's any update, or if there's a meeting or such.
