I felt this way before taking my current job, but I took it anyway. It turns out that you can learn way more way faster when you're working in a team on a real project.

There's _a lot_ of stuff that your teammates can teach you in five minutes that would take a day of Googling and experimentation to learn yourself, especially when you're a beginner.

What if there was not a team? Just one person.

Even then I would approach it with confidence. You can learn things very quickly by doing, especially when highly motivated and especially if you can budget some extra time (perhaps unbilled?) to account for the learning curve.

I would only turn down work for fear that you are not capable if you know it is truly beyond your ability for the forseeable future or if the deadline is too constrained to permit yourself to recover from mistakes or delays from learning.

Then you get more pressure. You want fit where you are, don't want to let anybody down. And from the inside you get second breathing and try try try, and one day you see that you are far away from your start.
