To find the best scholarships, I always suggest to start with a simple Google search  
“Scholarships for (Louisiana) students”
"Scholarships for (Jefferson) Parish seniors"
“Scholarships for (computer science) majors”
“Scholarships for (Hispanic) students”  
"Scholarships for (swimmers)"  
Of course change the parentheses to make it personal to you.
But this will bring up websites that will show more personalized scholarships to filter through and see which ones you meet all the requirements for.  From there, put the links into this scholarship organizer to keep track of all the deadlines, award amounts, and details.
