Charity Giveaway

I'm participating in the Extra Life gaming marathon for a children's hospital. All donations are made directly to the hospital with no admin or other fees taken out.

I'm trying to raise awareness of my donations page and get a little bit creative with ways to raise money. I was wondering if I were to do game giveaways on here, would there be any interest for the community to here to make donations. Do you guys think this would be successful on here or not? I was also thinking about possibly doing exclusive giveaways for people who have made donations. Lets say if I asked people to leave there Steam ID's in the comments of the donation, and I make certain benchmarks ($25, $50, $100, etc.), I can give away games to those who donated exclusively (randomly selecting).

So, do you guys think this would be a good way to raise donations or do you think this would be unsuccessful? Also, if you have any other ideas for ways to raise donations, feel free to comment, I'm all ears.

Thank you very much in advance!
