I could recommend NextStudent.com. They offer a Scholarship Search Engine that houses more than 5.9 million scholarships valued at over $16 billion. Using the NextStudent database to find money for college is fast, completely private, and totally free of charge.They won't spam you or send you anything like most scholarship search engines.
What I would recommend is after looking for scholarships if you need more money for college (which most of us still do) I would then recommend looking into a private student loan. Private student loans should only be taken out after you have filed for Federal college loans, scholarships and grants. Private student loans will help you fill in the gaps to pay for the additional college expenses we all have; room and board, books, food, etc.
Hope that helps. Good luck in school!
