There are multiple ways in which you can locate a piad internship. First, participate in any on campus career fairs that your college conducts. There are usually career fairs in both the fall and spring semesters. At some schools, there are career fairs specifically dedicated to internships. Attend these fairs and interact with the reps from those companies that you are targeting.
Second, search for internet job postings for internships. There are multiple sites at which these can be posted, but the most effective way is to use a job board aggregator such as indeed.com or simlyhired.com. These sites 'scrape' other sites on the internet for job postings and provide you links to the postings that are of interest to you.
You can also seek out internship opportunities by building your professional network. This is important when looking for a permanent position, so it is a good idea to start this now. Go out to LinkedIn and search for people in the field in which you are interested at the companies that you are targeting. Attempt to connect with them through LinkedIn and when this happens, reach out to them and inquire about internship opportunities at their organization. Networking takes time and patience on your part, but if done well, will pay off nicely for you.
