My services include data entry, Virtual Assistant, lead mining, email sending, article writing, proofreading/editing, telemarketing, designs, and more. As an experienced BPO professional (though my team and I cannot please everyone), I (and my team) have worked with numerous companies worldwide in areas such as lead generation, sales, customer service/support, data entry/processing, VA, and research. I offer many services, including telemarketing, customer service, graphics design, logo design, branding, technical support, data entry, and more. I was featured on Freelancer a few years ago (together with my small team) and have been a Preferred Freelancer here for more than a decade (but still stayed grounded and low profile). If my qualifications match your needs, please consider our small company for your next project. manj -
