Find and use friends that have similar products or services

You need to find and use friends that have similar products or services that would be an awesome supplement to your business. To offer a mutually profitable cooperation. Add their product/services as bonuses for those who order your product. The same can be done for your friends. When someone buys your product or service, he/she will get the bonuses from your friends for free. Be sure to add the element of urgency. The offer should last for a short period.
