You will find that unless you are a nonprofit, in basic research or daycare, there are no grants for a small business. For further information, go to http://www.grants.gov/ and follow the instructions.
Some cities offer grants to small businesses if they will locate in the downtown area or want to upgrade their store front, for the purposes of building up downtown traffic. Check with your City Hall for details. Private foundations offer grants. You can get a list of most US Foundations and private grant sources at http://www.foundations.org/
Any bank will require a business plot that shows that you can pay the loan back. Go to http://www.sba.gov or http://www.score.org/resources/tab-a for instructions on how to write a business plot and sample business plans. You should have a credit score of at least 700. You will personally have to place up 30% of the funds as no bank is going to assume all of the risk.
