If you're planning to immediately market to your target customer segment you're doing it pretty wrong since you almost certainly don't have product market fit yet. You should be talking with them, asking questions, learning, and trying to understand their pain points, existing solutions, & decision making processes. I recommend the book The Mom Test here. Marketing comes after all of that and there are many posts on how to do it with small ad spends, a landing page, and an email signup form.
