Congratulations on taking the first step! As someone who's also building a business, one thing I've learned is that having good systems from the beginning can save you a lot of time and frustration later. I would also recommend focusing on clear communication with customers, building your reputation through quality work and reviews, and not undervaluing your services just to win every job. Growing while keeping your full-time job sounds like a smart approach. Wishing you all the best on your journey—I hope your business takes off!
