Hi,
I am not sure which source of income you are looking for, but I can offer to sell our services to the businesses around you.
We are a UK based company that specializes in EPoS and eCommerce solution for small business.
You can sell our software (and/or services) along with the hardware from Amazon to the corner shops or similar businesses.
Let me know if you are interested and I will provide more info.
Kind regards,
Aram.
