Great to have you here, @PATIENCE.
Each of the donors listed above have their own procedures and requirements, so you’ll want to click through to their websites to learn about them. You can then get in touch with the ones that seem like a good fit for you.
I suggest you also look at who else is working on legal empowerment in Sierra Leone and get in touch with them, to find out how you might work together. That might be the easiest way towards donor support if you don’t already have ongoing projects and a track record. You can also get to know people who are talking about #sierraleone here in the forum and engage them in conversation, and contact them.
The member directory might also be a good place to find potential collaborators - just filter by Sierra Leone to see who is working in your country.
