You can make a lot of dollars by adding the capability to donate online to your website

If you are a 50l(c)3 (a certified non profit company) , you con accept online donations through the renowned network for good (http://networkforgood.com) . People feel more secure to give their money to your website with a NetworkForGood stamp ! It allows you also setting up a charity badge with pictures ,videos and text to raise awareness and money for any cause you care about ,Network ForGood also sends automatically thank you acknowledgement for donors –less work for you-. Here is an example of agency’s website of a qualified Network For Good Company : http://www.rainbowheights.org/donate.php 

If you don’t have a 50l(c)3 (Not qualified for Network For Good) you can still receive online donations through the for-profit Paypal (www.paypal.com) . Donors don’t have the same assurance that you are truly nonprofit , but is still easy for donors to donate to your website by just clicking on “Donate” button or sending  a check (see a donate link with paypal : www.imanihouse.org/donate.html)

You can also use a new popular trend in online donations which is ChipIn (www.chipin.com ),all you have to do is to fix the amount you want to collect,for what and when and then pick up a code of your personalized widget that you can embed in your website or for your email signature (The chipIn widget displays a thermometer showing the current level of giving and so inform donors in real time how their donations gets the project closer to being funded and happening)

Finally , The more your reasons are convincing the more donors are going to act to your favour , so be sure to write up some success stories or how donors can make physical changes to your clients and put this on your website (I recommend you this website for a good example : http://www.irishouse.org/donate.html  )
