There is a simple flu drug currently undergoing phase 3 human trials that has been shown to be effective against Ebola in animal tests, but is not FDA approved for human use.

So far I have been unable to find any source to purchase this drug. Presumably it can be synthesized from the commonly-available prescription drug Pyrazinamide, but the description of the synthesis and purification process that I was able to find seemed a bit over-the-top for an amateur chemist.
The effective adult dose for Ebola treatment should be 1600mg twice on the first day, followed by 600mg twice on days 2 - 7.

In case that was unclear, the initial loading is 3200mg on the first day, and then 1200mg per day for six more days. Animal trials suggest that your immune system should be able to clear the virus from your system in that time.
Treatment should begin at the first indication of exposure. If you wait for the symptoms to appear, or worse, for a confirmed Ebola blood test, the drug should still help your chances for survival, but the damage would be extensive and the recovery would be difficult.
