Hi,
Trying to boost financial during times in pandemic is really hard. Since we are not allowed to go out, thinking the best way to do business at home Is Ideal. Selling healthy foods at your door step is relevant and timely in this time of crisis. I live in asia particularly in the Philippines, i don't know If selling goods in your backyards in other countries are allowed but in the philippines it is, this is what we so called "sari-sari store", you can find allot of this in every filipino houses.  I think this type of business if very timely, you get to sell goods by just staying in your home and At the same time you get to help your neighbors with some of their daily needs instead of going to the malls which is so crowded and the risk of exposure to the virus is high.
I was impressed with my neighbor who is my inspiration in doing this content because i was about to buy a vegetable and there are only 2 pieces of it, then he ask me if i want more because he just have to grab some in their backyard. So basically he is selling fresh veggie just right in his backyard. Allot of our neighbors is going to his store since they know he is selling his own Planted veggies. Great business idea, vegetables and fruits are really necessities now A days since pandemic happen so it is a great product to sell.
So if you have a space in your backyard and start planting, you get to benefit in your own health and at the same time it is a good start for a business.  It just need a little capital if you will have to purchase seeds. But this type is business is not something you get to have a huge amount instantly, You have to work for it, hygiene of course is very important, you have to show your customer a clean store and attentive to their concerns. Since you are about to start a small business some will have to observe you before you get their trust so just work for it.
Important thing is that you get to earn safely just by staying at home :)
