How to find a cheap editor to cross-read before sending it to an agent?

Have you got any friends you could ask to look over it? Ask them to read through your work and give an opinion, watch for grammar etc.

Another option might be looking on websites like www.fictionpress.com/ (an original writing site) to see if anyone would volunteer to edit it. People often 'beta' each other's work on sites like that.

Actually the agent is the one who sends things to the editor. Editors practically never look at stories sent in by the writer.

Well first off, the publishing company provides the editor. You are looking for a beta-reader. You can find them all over the web but it's best if you ask a family member of friend willing to do it for you.

I think you'll find what you want here.
