I read.....
Lots of confusing text, and in my mind you'd end up with some Frankenstein of a site with various bits from all over the internet, with no particular direction or style. Lots and lots of wants and don't wants. Lots of what sound like a major pain in the ass to get any real design out of. It sounds like there could potentially be lots of back and forth and changes and unsure about various things, wanting this and that but not this or that.
Frankly, just reading your post has given me a migrane.
But to end your post with "Thank you tell me your cheap offers" is pretty insulting to any designer given your list of specs.
I highly recommend those who DO bid on this, to bid HIGH as the SKY, and be very specific with the number of changes you are going to give for the price you quote.
Not to be a dick or anything, but if I did freelance, I would just pass this headache up.
It almost sounds like maybe you should just design it yourself.
