i need a circuit designer

[canada99]

dear sir/madam

i have an idea and i am planning to do the circuit for it. and i need your help if you can.
my only concern now is whether there is a possibility to store around 700 MB "approximately a CD" to store this quantity of data on a chip "compressed recorded voice in Ra extension files", the data would be saved only, and there would be no way to add or delete the data, then i want to be able to read this data and listen to this through small built in speakers.

the whole product should be very small in volume, and also the price is a concern as i might make thousands of this product.

thank you for you time
