Social Media Content Creation

I'm looking for someone to create x30 social media posts, with images (sourced from royalty free websites - I have some saved already) with a mixture of messages.

The content is for a charity who refurbish old laptops/computers/tablets and provide them to families or people who need them.

So the messages would be:

Asking people to donate old laptops etc
Raising awareness of what the charity does
Finding relevant content which could be shared (links to news stories about digital divide, recycling/green initiative, etc

It would be good to see if you can think up some original ideas for this and please send me some examples of your previous work if possible.

I will send full details of the charity to the right candidates.

Thanks,
Clare
