I want to raise money for a candidate

I looked at your profile and noticed you're from the Philippines. Well, I think those politicians there are capable enough to raise funding for themselves considering most are corrupt anyway. You must be very passionate about what you do then. To start, you can probably organize a group in favor of your selected candidate and go from there. If you can find people working with that candidate then you can try and see if you can coordinate with them in the fund raising process.
