wordpress programmer to add some new stuff to

I need some advanced WP programming to add fields to forms already in place, to make certain forms not show up on the website if there is no data for that particular field, add dropdown options to a couple fields, just a lot of advanced WP and PHP stuff I have no idea what to do. Must have very advanced WP and PHP skills and know how to do very advanced programming things. Must be able to start immediately, and make progress in 24 hours.
