[Cash-and-caring] questions regarding conducting an online raffle

[Craig Cooper]

Greetings,
I am attempting to put together a "meet the blind" event for our local
chapter.  We are trying to work with a local Walmart to hold this
event and sell 50/50 raffle tickets, as well.  I would also like to
sell tickets online and use Facebook to promote the raffle.
If you have conducted online raffles, were they successful?  Please
share any tips and suggestions.
I have seen affiliates using this web site:

http://ulwxastpyh.formstack.com

Is this the best site to use, to host this type of online raffle?
Thank you so much.
Craig Cooper
