Hi everyone! Looking for some direction from someone who's possibly done this before! I have Googled and researched for the last 6 nights in a row and every night I just confuse myself more and more. 
Basically, I've written and illustrated a children's rhyming book that I'm very proud of. Although I've written lots before, this is the first thing that I've been excited about and would like to send away to publishers. I have a few questions.
- I've done my research and found some publishers who are taking unsolicited email submissions. Do I send the whole manuscript plus illustrations away all at once, or should I send a query letter first?
- Although I am technically a graphic designer and have had some design work published, I have never illustrated a story before. Is it worth sending the illustrations away too? I know most places are very strict about this, and don't want to see amateur pictures. (Is it worth posting a sample pic here for you lovely MNetters to judge?)
- Is it worth trying to find an agent before sending this to publishing houses? Can you even get an agent without having any work published before?
I'm so sorry for the long post. Any help would be very much appreciated!
