Use "could" for possibilities in the future.
Here’s an example of could to talk about future possibilities:

“Do you have any ideas for our publicity campaign?”

“Yes, I’ve got a few ideas. I could put advertisements on Facebook and Google. We could also give out pamphlets in our neighborhood. Maybe John could even contact local TV stations.”

Use "could" to make polite requests
$\bullet$ Could you please open the window? It’s hot in here.
$\bullet$ Could you turn the music down? Thanks.
$\bullet$Could you make 10 copies of this report, please?

As for "would"...

eclipsedstar · Answer

Use "would" to talk about unreal or unlikely situations.

Examples of this:
$\bullet$ If I were the president of my company, I would make a lot of changes.
$\bullet$ If people were more generous, there wouldn’t be so much poverty in the world today.
$\bullet$ She would travel around the world if she had more vacation time.
