"Where can I get free grant help?"

The suggestion about doing some research at the library was very good and I will even take it a step further and suggest you do your research online.  Over 90% of grant program information I have found online and since you have internet access you should use the Internet.

I'm also sorry to tell you that the non-profit that you mentioned is EXACTLY the type of program that gets grant funding(s).  Now you can either find an organization that does the same thing that yours does and ask them how (and where) they got their grant funding, you can ask someone that specifically does this kind of work and ask them to provide you freely with the kind of grant information that you are looking for and then there is the additional option of attending community seminar-like lectures - that are free - that are being held in a lot of communities.
