Free Minecraft Server Hosting?

Okay.. So I have started my own Minecraft server, and want the best out of it... I don't ave the right hardware though.. My computer can hold about 5 people with a little lag. But that's it. I was wondering if someone could host my server.. I would greatly appreciate that! When I receive donations I would repay you, then give you full permissions to my server, also recommending you too the WORLD! I would greatly appreciate that! PLZ reply!
Thanks!
