Stickers are a good idea to start a business in a not-so-popular city. If you are located in a huge metropolis, then such a business will bring very little money due to competition and more profitable and large-scale offers.
I started my business this fall after reading an article about best business ideas and I liked one of them.
I chose banner printing. This is a bit like your business, because I understand how you can start all this now!
I had some problems starting this business, I couldn't find a good supplier of materials. As a result, my colleague from a previous job helped me with a good supplier in my city.
You need to find good printers to get high-quality stickers, otherwise no one will buy them. This is verified since I bought the very first printer that was cheap. My advertising banners were of really poor quality. After that, I took better printers.
