Allow user created pages

Hi all. I am the developer of a platform where companies can post internships online for students. Currently, in the posting process, companies fill out a google form that I then copy the information from onto a new page I manually create and link on the our website. However, I am hoping to automate the process to allow users to submit a posting by filling out a form and have a new page be automatically be generated. I was wondering if php code can be injected into Squarespace or if there is a way to implement a feature where visitors can submit information to auto-generate a page on Squarespace.

I would suggest looking at the blog feature. It allows for multiple contributors but they have to be manually added. There may be a way to rig it to work for you tho.
