English isn't my first language, so I don't know how to express what I am thinking, but yeah, like you said. All the developers I find on Upwork, Freelancer, and Reddit are basically useless. They ask for too much money and want a regular license, which is something I won't agree to until the site reaches one year. Where can I find experts who will do this work without asking for a bucket of money and a license?
Despite not being a native, to avoided complications, with little effort you could compose exactly what you need done by a developer. Through the information, the coder will know the complexity of your task, whether it's simple or difficult, if you'd need a plugin or not to achieve your goal. Looking for good developers, I'd refer GitHub, though Private messages are not enabled, but some share emails on their profile, also traces of contacts are found on repositories. You'd also need to be logged in. Between do you run a WordPress site?
