More specifically, on Twitter, many people post requests for help. You can directly reply to these, as long as you don't come across as too pushy. For example, if you fix laptop screens, search for people in your area who are looking for a laptop screen repair. Then offer your help in a public tweet. To perform this type of search, visit the Twitter website and type your search terms into the box at the top right of the screen. Next, look for the Search filters sidebar and hit the Show link that you see next to it. A drop-down menu, which includes a location option, will appear. Then select Near you to filter for those who live in your region.
