How do you outsource content?
Interview your writer and ask several attention check or comprehension question. Just to make sure you teo are the best fit for each other.
Outline your budget and the scope of the project you are hiring for. Make all available documents easy to access so you can review them with your candidate or have them review on their own time and let you know if they have questions.
Should you outsource content creation?
Depends on if you have more capital or time. Because time is your most valuable resource but you should learn how to write the content first and create a structure that you like and use that structure and see which writer can best replicate that for your price point.
