You need to provide a frame of reference for your business.
- Are you a cook yourself and want to host pop up dinners?
- Do you have an army of chefs trying to cater to family events?
- Do you want to get money from ads on a cooking blog?
- Do you want to earn youtube revenue? (for this I'd say go specific rather than generic because there's a lot of there)
I think creating a Youtube channel would be much better, I mean I know I wouldn't literary pay for watching someone cook, and I think you can earn money from Youtube as much as a freelancers and 10 times more
You could go and create a nice looking website, offering your services around your local area. YouTube is also very helpful, although I think most people will watch your videos to check out your recipes, not to hire you to cook for them.
