There are many ways to pay a freelancer, generally speaking you can pay by: 

• Project 

• Hourly Rate 

• Monthly/retainer rate 

For a video editor freelancer, you can: 

• Pay for a single video (per project)

• Pay for a series of videos (collectively as a project) 

• Pay by the hour 

• Pay by the week/month if also possible (this oftens if a video editor can provide you with an estimated number of hours or videos that be produced in that time) 

For a virtual assistant and/or social media manager, it’s more often to consider a weekly or monthly retainer with tasks more clearly defined. Don’t worry, this doesn’t mean that you can’t change the plan at all. Just keep in mind that by adding something to the list of tasks probably means that you’ll need to 1) pay more, or 2) remove some tasks off the list. Once you establish a relationship with a good or a great freelancer, making these changes won’t be as annoying as it sounds. 

For example, Upwork.com allows you to provide a budget for any of the options above, which makes hiring even easier.
