How to get experience

Hi I am a critical care nurse in Wisconsin and I am interested in learning to place PICC lines. I am very willin gto take a course to become certified to place PICCs however, I do not know how to find someone who would be willing to precept me. The hospital where I work doesn't do this. ANy ideas on how I could learn? I am willing to do this unpaid! And i am willing to do a little traveling to learn.
Thanks!!
