Can I have a piece of your Sourdough Starter?

Calling all Seattle area friends! This week I would like to make sourdough pizza. I have been doing a lot of research about making my own starter but I am weary.... I know it's best if it's been going for a while and I won't have too much time to feed it before I want to make the pizza. Does anyone already have one going that I could have a piece of? If so, I'd be very grateful!

I may also check to see if I can buy one from Macrina or QFC but I figured I'd ask my friends first!

Thank you! <3 Sara
