Welcome to cos.com ChocoPanda! Sadly, I don't live in your area, but I hope you find some local cosplayers! I encourage you to go to the con even if you don't have someone to go with because you'll meet local cosplayers there to hang out with at the next con!
I've seen and like all of the anime you said you like! K-on is awesome! Mio is my favorite character from that anime.
My favorite anime are: Mahoraba (Almost nobody's heard of it), D.N. Angel, Chobits, and Clannad.
I started cosplaying in 2011 and I still have a lot to learn about cosplaying in general. Being a new cosplayer made me nervous because I was worried that people wouldn't like my cosplays, but the cosplay community is really awesome and I've always gotten compliments on my outfits. Sewing has been my most important, most used skill. Now I'm learning prop making.
