First of all, I'll tell you the objective facts. Surrender is not that simple. Nowadays, there are many writers. If you think your writing is good, try to mail the manuscript to some magazines first. If you want to contribute online, first go to some online novel websites, where there are service centers and behind-the-scenes editors. You can give him some of your own manuscripts first, and then he thinks it's ok. You can sign a contract with him and give him all the manuscripts.

I wish you success.
