Sites like Cookening, EatWith, and MealSharing are to restaurants what Airbnb is to hotels. Sign up as a host to earn dough by cooking and serving meals to guests in your home. It's up to you what you want to cook and how many people you can accommodate. Cooks are paid directly through the site, so no cash ever changes hands. The earning potential for becoming a cooking host is $50-$100 per meal.
If you’re new to blogging, and want to learn how to make money at home but aren’t quite where to start, I’d consider starting a WordPress blog (like this one) with HostGator. It’s a low cost way to start your own online business (less than $5/month) and HostGator offers a 45-day money back guarantee if you deciding blogging just isn’t a good fit for you.
