First post, let me know if I'm doing something wrong.

I work as a "freelancer" / contractor for design agencies in the US doing web development. I've been doing it for close to 5 years, and each year until the last 2 have been growing:

1st year was 24k

2nd was 48k

3rd was 65k

4th was 98k

5th (this year) is 100k

I feel like I'm running out of steam though. I feel like I can't raise my rates, and my client base is fantastic all around. Great people, quick turnarounds, etc..

But I don't want to stop at 100k. I just don't know where to go from here. Has anyone else gone through this and overcome it?
