Making money isn't as easy as it looks like, for me personally it took me 3 months to make my first money, that doesn't mean you can't make your first money in 3 months. I personally do freelancing (video editing). When you try freelancing don't use cheap and competitive platfoms like Fiverr and Upwork, I use twitter (or X) and Discord to get my clients. Since Fiverr is way too competitve, Instagram theme pages is indeed a good business but again it won't make you money fast, once you haave builded a good audience you can monetize it, now I don't know if you're looking to start a real business or make some fast money, but most businesses requre you some money to start. Theme pages and TikTok CPB you can start with no money.
