We know that every creator is unique and as requirements vary, so do prices.
In general we work to a fixed price which is either
A weekly fee for a given number of videos
A price per individual video (which can be calculated as a set fee for every video of a given format, or by raw footage time)
Prices reflect the turnaround time, quantity of work, technical expertise required, and a few other factors which can be explained specifically for your content on a call.
However, if you're just looking for a rough figure, it would be $100-140 USD for a 4 hour vlog or gaming edit, depending on the above factors.
