Well, the general idea does sound fascinating. Before taking this price as fixed or actually agreeing, though, I will need a lot more information as to what your aim is, what word count you were thinking of, who the target audience is etc.
I would definitely be interested, though, judging from what I've seen so far.
Feel free to contact me any time, I am definitely looking forward to it.
Sincere greetings,
Katharina Stein
