Online Microlenders
"Kabbage is one of several online microlenders that offer short-term capital to young businesses."  (p.74, Entrepreneur, January 2013).  You can borrow $5,000, $10,000, $15,000, $40,000, $60,000.  

In addition, the SBA microlender program is a good source, so look up your local office or go to their website.  Read about SBA here:   http://www.ibj.com/microlenders-aim-to-help-businesses-grow-survive/PARAMS/article/38837

There is a top 10 list of microlenders from CNN but it's sort of dated but may still be useful.  http://money.cnn.com/galleries/2011/smallbusiness/1107/gallery.top_microfinance_companies/
