If you're interested in working together, let's start with a Skype chat. This is completeley no-strings attached: it's an opportunity for you to get to know me a bit, before we decide on working together, and for me to get to know you, your background, and your plans for the book. This relationship and understanding is invaluable for working together successfully on your book. I can also give you more advice about what kind of help will suit you best at this stage.
Once we've spoken, you'll be well placed to decide what path will suit you best, and whether or how much support you want at this stage.
