Hi Jake, hope you're well.
I've read your proposal, and I'd be very interested in working with you. As most of the work involves copy and pasting existing text, I don't see any reason to charge more than your $8 minimum.
I see you have preferred HTML colours - would you like completely different designs for each ebook, or are you looking to produce something across a standard template that will work for everything (e.g. are you trying to create a corporate identity, for want of a better way of putting it?).
Please do get back to me, I'd love the opportunity to discuss this further with you - I'm sure that we could have a very productive working relationship.
Kind Regards,
Ali
