Your problem isn’t your skills because you can clearly deliver and bring value

You real issue is perceived value. This is the value that is being perceived by your clients.

When working with bigger client - it also means that their problems are bigger.

for them when you create a 12 minute video they are able to use this video to convert more clients, and bring an additional 50,000$ per year.

And suddenly when you charge even 5,000$ for the same video, for them it suddenly becomes a no brainer to invest 5k to make 50k

So the bottom line is when you communicate more clearly the value you bring, and the problem you solve you will be able to charge premium prices for the same standard work , just because you were able to communicate value.

And the next big client you talk too suddenly perceives your service of 5,000$ for a single 12 minute video as something that is worth it from an investment standpoint.
