I remember years ago when one of the members of an FB group I joined talked about how he got offered a deal by a popular local car accessories store. In exchange for monthly discounts and freebies, he agreed to placing the store’s name and emblem on his car (via car wrap sticker). So pull out your thinking hats and get creative! Who knows, you might just land a sweet deal.
If you're a graphic designer or even an amateur artist, there are plenty of sites which will pay you for sharing your artwork. Sites like Etsy, Zazzle, and The Souled Store allow people to add their designs to T-shirts, phone cases, mugs, posters, book covers, and more. If and when these products are bought, the sites then pay a commission to the contributing artist.
This would only require the investment of your time. Start with a blog on something you love. It could be anything. From a travel blog containing pictures of your travels to a sports blog dedicated to your favorite team/sport. You can blog about anything and everything. It doesn't matter. But write regularly!

India's gross domestic savings in 2006–07 as a percentage of GDP stood at a high 32.8%.[206] More than half of personal savings are invested in physical assets such as land, houses, cattle, and gold.[207] The government-owned public-sector banks hold over 75% of total assets of the banking industry, with the private and foreign banks holding 18.2% and 6.5% respectively.[208] Since liberalisation, the government has approved significant banking reforms. While some of these relate to nationalised banks – such as reforms encouraging mergers, reducing government interference and increasing profitability and competitiveness – other reforms have opened the banking and insurance sectors to private and foreign companies.[209][210]
These days, low-risk bond yields aren’t enough to meet most income needs. When investing in bonds, the income typically comes as coupon payments – contractually guaranteed interest payments at predictable intervals.  There are many kinds of bond income available, so you must strike a balance between reaching for higher income (yield) and limiting risk.
