What you are looking for is "one class at a time grant". See http://www.cbs42.com/content/oneclass/default.aspx if this helps...
If you are from Texas, also check this http://www.harlingen.tstc.edu/financialaid/FA-FAQ.aspx#q9
See if this helps...
I could not find much. Try http://policy.gmu.edu/Home/StudentCareerServices/ScholarshipsFunding/ScholarshipsforPhDOnly/tabid/149/Default.aspx
and see. Let me know if this helps or else I shall opt out and let other expert assist you.
I wrote and applied for monies from this site. I have not heard from them. i need monies like yesterday.
If you have not heard from them, kindly follow it up with them, as there are very few options that would give you grant for this. Try and follow up and put in 3-4 more days of active follow up. If they refuse, kindly take the reason, or when you follow up, they will give you some reply, which is important to know.
Let me know,
