My first advice is figure out what type of marketer do you want? There is a huge difference between a business development specialist and an online marketer. Generally a business development specialist is focused on distribution, partnerships, sales, and potentially affiliate programs if you are lucky. A traditional internet marketer will be focused on SEO, content development, user experience, email etc.

My advice is that if you can make the time you should start looking now, even if you are not ready to hire. It is going to take some time to find the right person to mesh with your personalities and if you do find a great person they need to be as excited about your product as you are.
