You are describing building an entire website. Something of this programming depth is thousands of dollars. Unless something here is getting lost in translation.
If you want to speak more privately you can e-mail me firstname.lastname@example.org
. Do you have any parts of the website online yet? If you do e-mail me the like or send a screenshot.
One last question, do you already have the script and need someone with PHP knowledge to get it running on your site?
