freelance/contract guidance please!

Hi all,

I recently lost my job in social media marketing due to my agency losing clients and no longer being able to afford to pay me. I worked there for 3 years but only spent about a year on the social team. I also did influencer marketing, data analysis, and PR with the agency. This was my first job out of college.

With this new free time, I've been diving deeper into more aspects of digital marketing and have been learning a lot. I've also been spending time at my old high school nonprofit job as a volunteer. This nonprofit is a local historic site and doesn't have a lot of money to spend but I love the place, which is why I volunteer. In high school (about 10 years ago) I worked there as a tour guide and made $7.25 an hour, which I'm pretty sure is what they still pay tour guides.

The site director texted me today asking how much I would charge for contract marketing work and I have no idea what to ask for. I don't want to throw a number that's too high for them when this could be a good opportunity to further build my portfolio, but I'm also not wanting to make minimum wage. This is in Wyoming in the USA. I'm married and my husband has a great job as a software engineer so I'm lucky to be in a stable place where I don't have to worry too much about monthly expenses, etc.

Would asking for $15-$20 an hour be fair to both myself and the nonprofit? Should I go higher? How can I negotiate if they come back with a lower offer? Any guidance is super helpful 😊 thank you!

TL;DR I'm unemployed (in the US) with an offer from a nonprofit to do contract work. What can I charge for this work that would be appropriate and fair?
