Looking for 200+oz in Seattle

I have also posted this in the Washington section, but wanted to post here as well.

I have a 4 mo old, who I have been able to exclusively breastfeed until now.

I recently suffered a severe illness that has reduced my milk supply by about half. It seems that nothing I try will bring it back up to where it was before, and it is getting to the point that we are going to have to face the fact that I probably won't be able to supply all of his milk. My husband is pushing me to look into formula, but I want to avoid it at all costs. I was so happy to find this site, in hopes that someone could help.

I am willing to pay for shipping from anywhere in the US, along with packaging costs.

I am hoping for at least 200 oz, but of course, will consider any offer. If I can at least get enough extra milk that he's supplied for a few weeks in combination to what I can pump, I can focus on getting my supply back up without the incredible stress of knowing that my baby isn't getting enough to eat. He's only gained 2oz in the last month and my pediatrician let me know that I'm going to have to do something very soon, as my efforts to up my supply aren't working.

I am located in Seattle, and am also willing to drive if it's within 50 miles. If it's farther than that, I would most likely prefer to pay for shipping.
