I need a script that can handle the following tasks.

Take user data from my database and fill in and submit / post data to forms located on third part websites.: So I want to know if is it hard to create or do somebody knows if does exists some script for mass form submissions in PHP -Javascript-Ajax ? I run Dancers & Hostess & Model jobs website, I would like to find some script which allows the girls automaticly submit to hundreds websites forms (other 3rd part model agencies) with their similar model application form info on my website previously specified,

• 1).Firstly the girls will fill out my agency portfolio very detailed form , like this i will get all the model personal info from them ,

• 2) Secondly i would like to allow for example models to submit to 100 and more other model agencies
  forms (I will find those websites before, and I will get their field names = values
  and thanks to some script would like to connect them with every girl data already created in my website to
  submit .

I would like to implement it to my wordpress website where the girls has their portfolios instead of my pages . I would like to offer this service especially to models , it should work like some directory submitters , The script knows names - values and fill it out itself, but I want it online - browser side, where the girls should only fill out captcha if there is and click the button "submit".After succesful submit it should offer other form to submit. I would be very happy if you know the answer or if you can redirect me to some article
