Here are a few sites that have FREE scholarship searches.
Be aware of scholarship scams! Never pay for someone to find a scholarship for you - there are lots of free resources. Also, be skeptical of anyone who "guarantee" you'll receive scholarships or loans. If you are unsure if a scholarship/scholarship service is legitimate, see your counselor or check out Project Scholarship Scam at http://www.ftc.gov/scholarshipscams
