First of all, is tech work what you want to be doing? If so, then you got a little taste as to how it will be working for actual clients in that area. If not, you stll gained some experience and know where you stand on that.
I think you have to consider this as a learning experience for yourself. You sound like you learned some valuable lessons.
Also, remember that an agency probably won't pay you what you are worth. On a positive note, you were able to play around with your skills and make some self-discovery.
In all of your jumbling (which I didn't think you were doing - and I am very good at doing that myself, too!), I think you just answered your own question.
