Help Launch a Talented Young Creator's Dream

I am a 70-year-old retiree who wants to help his 19-year-old great-nephew start a business. Unfortunately, my only income is partial social security. All I can offer him is my support, my past business experience, and a lot of love. He has designed over 95 paper products made for consumers and businesses that increase productivity, help people become better organized, and can identify people and property. These products can be sold worldwide via the internet. But startup costs, including an eCommerce website, advertising, etc., are very expensive these days.

Any assistance would be more than welcome and greatly appreciated. Thank you for your time and attention.
