1. Setup your own part-time business from scratch:
Here, you can start with anything that is product-driven and extremely easy for you to fulfil on.

It needs to be something that you believe in, you feel confident about selling and that you can promote on a 24/7 and automated basis.

Something that will not force you to spend a lot of your valuable free time on things such as customer service.

2. Start your online venture with Affiliate Marketing:
To tell you the truth, affiliate marketing was a HUGE revelation for me, and got me super-driven right from the start.

In this model, you basically sell other people’s or businesses’ products and get a commission in return.

You are obviously not required at all to be involved in the production or delivery process. Plus, there is NO RESTRICTION to the number of products that you can promote.

So, when it comes to the income streams that you can generate for yourself, sky is truly the limit here.

This is the most ideal option if you're interested in pursuing a side venture (without giving up your current job, at least immediately).

3. Sell your physical products with E-Commerce:
Another option is to sell your physical products with an E-commerce business.

Rest assured that you don't have to reinvent the wheel. You can order existing products in bulk at a very low cost and then set up your very own sales system.

Or you can design your own products, employing a variety of fantastic online tools, and have them efficiently produced for you remotely, according to your specifications.

Then, platforms like Amazon FBA will do the heavy lifting for you. They will process all payments and deal with the packaging, distribution and customer service. In the meantime, you can focus on setting up your marketing campaigns to sell your products – which you can do around your job, committing just one or two hours of your time a day.
