Ask HN: A web-based PDF editor?

I am getting a wedding brochure made and need to go back and forth on the PDF design with the publisher.

For some reason, Crocodoc has a 25 MB limit and my file's bigger than that.

Using Adobe's web app is worse than stabbing myself in the eye.

Everything else I found on google doesn't work or looks too spammy to trust my document with it.

Are there any other options?

If not, can anyone please build this for me? It is a weekend after all...
