How to search through multiple instances of same image on same webpage

Hello Experts,
I have to search a site for ‘Job Consultants’ and for each page they give 20 listings. against each, there is a phone icon, clicking which we can send message to the consultant. after we browse through 20, there is a button to load another 20 under the already listed one’s. this way the list will go on.
What I want to do is to browse through all those and for each, click on phone icon, submit my details and the click on next. once this is done for first 20, I will load next 20 and continue.
The problem is how to browse through. please help.


Can anyone please help here?
