From the Lawrence website:
We encourage you to look into potential funding sources outside of the usual aid you receive. The more creatively you think about potential funding sources and the more research you do into this, the more likely you will be to find funding support. There is no magic solution or definitive database of funding options so it’s up to you to search out different sources. There are lots of scholarships available for study abroad waiting for applicants. This page provides some suggestions for your search but you can also do your own internet search, consult various civic, social, or religious institutions (such as the Rotary Club), or check with your parents’ workplaces for possible scholarships.
