The thing is, my publisher is American. Do I need an English agent to help me or will they just take a percentage of my possible earnings and not be of much help? I kind of thought it was the agent's job to get you a publisher. Or, if I do decide to get an agent, will they be easier to get as I already have a publisher? And as my publisher only does adult books (for grownups I mean, not that they are 'adult' content!) would getting an agent help me to get a publisher for my other books - which are more older children and YA?
