Technical writer (+tester)

You should be able to describe WordPress themes or plugins

It’s an ideal job for somebody with tech support background (web design company).

Here’s the process in a nutshell. I send you a WordPress theme, WordPress plugin, etc. You need to install that item on your server (localhost is OK) and give it a test (configure available settings, see how it works) and then describe the features and benefits of that item (WordPress theme, WordPress plugin, etc).

Then you just go through your write-up to make sure that you described everything right (mentioned all the available features and benefits of the item - WordPress theme, WordPress plugin, etc) and send the text to me. This job can take you anything from 1  to 3 hours, depending on the amount of work involved.
