Submitting a comic to grade at CGC

Hi

I have a Marvel comic that I would like graded. I have never done it. I went to the CGC site and looked at the process, it seems straight forward. Anything I should know from experience users/collectors here prior to submit?
I am a little nervous sending my comic.

Thxs a lot

Here's a video about it.
