I'm involved in a foundation/organization in the Philippines called "little hands" which helps poor children with their needs. We need to reach out to more people. Where do we find the people willing to donate? What's our target audience? And as far as paid advertising, which one is better - Facebook (or twitter) or google ads?
This is not a sarcastic comment: you hire a marketer or marketing firm that knows what they are doing. Marketing is a science and art that requires skill-- it's like a doctor/surgeon for your company.
You wouldn't do open heart surgery on yourself-- why would you try to do surgery on your company?
If you'd like more help, feel free to set up a call.
