Assign a submitted form to specific member

I am also desperately looking for help. I have a job board and I need job seekers to be able to submit a custom form that shows up as an application form to the employer who posted the job and also in their own profile as a job they have submitted. I can’t seem to find any resources on exactly that kind of code only how to create a members area.

Hi, I am looking for this kind of feature,

My requirement is as follows:

I have a 3rd party form, and I can embed that in wix, upon-submitting details in the form after succesful payment in form, entered person should have access to member pages. Is it possible?
