You can uses tools such as Wordpress for your website platform. MailChimp to collect email addresses. Clickfunnels to create funnels and landing pages that are completely automated. Stripe to process payments. These are just a few tools I use but there are many more options for each part of your business. Find the ones that work for you and help you create systems.

4. Save, build and run a bread-n-breakfast place. Look at airbnb Vacation Rentals, Homes, Apartments & Rooms for Rent - Airbnb for inspiration. My wife runs one (Firdaus, Naukuchiatal) , it is not an income as of now but if you are on it for enough time, it would be, when you grow old. It doesn't have to be a fancy and glamorous thing. It could be a  2 nice-n-clean room in a city where you live. If you have a big house, it could be a  part of your house.
I have had a LC account for almost 2 years. Invested 5k. A lot of very small loans. Unfortunately I had to invest though Folio FN. The fees reduce your return. Now, they are not even allowing that. My interest and return of principal are not being reinvested. I talked with LC and they are working on it for my state. Even if I can obtain access to the prime portfolio, I would only place 10 percent of my cash here and would reinvest for at least 3 years. I am still concerned about what would happen when a recession hits.
