marketing strategy for digital product

I am looking to hire a freelancer to develop and implement a marketing strategy for my digital product. I need someone with experience in marketing who understands the best ways to reach my target audience, which is B2C (Business to Consumer). My desired focus for this campaign is email marketing or social media marketing, so I am looking for someone who can generate automated email campaigns as well as devise campaigns utilizing other methods if necessary. This campaign is relatively small, so the budget I have available for it is under $100. I am seeking a motivated individual who can help to reach potential customers and grow my product’s reach.
