Hi!
Please have a look at my Profile Page for samples. You can read a few of the Reviews that I have received, and get to know me through them.
I can do your 100 articles about Musical instruments, in the way you want. I must add that I like music and am good at playing a few instruments.
The $50 is less for this job, but since this is about music, my favorite subject, I'll do it for you. you can read my articles, satisfy yourself about the fluency, grammar, and the interesting way they are written, and then you can release the payment.
Awaiting your reply.
