You don't need to use an agent.
See this post, and view this document. Also, use Google to fill in the gaps or read from page 1 of Part 9 of this thread meticulously.

Estimate how long it would take you to gather all the required documents, and then determine if to defer or not. You should be able to do said estimation within a week, if you carefully and critically go through all the links above. Best of luck.
