Whichever client base you want to work for, be sure you find a niche. By starting off with a broad audience, you hurt the chances of growing. By choosing a niche customer base, and building a brand around them, you can have a more personal connection with your audience, that can then turn them into real business. Remember, you're starting your own company - so, on top of your industry knowledge, you'll also have to be aware of the marketing and branding must-dos in order to have a successful business.
Unfortunately, homes and clients don't just fall into our laps once you become certified. You'll have to put in a lot of elbow grease to grow your brand through exceptional marketing methods. As marketing professionals ourselves, the best thing you could ever do for yourself, in any business, is to pick a niche audience and build your business around them. With the ease of social media, a niche audience allows you to create a brand and portfolio that attracts the people you want to work with.
