For starter, you can apply the framework that you used to sell a product in your eCommerce business, to selling a brand/website/company to potential buyer/investor. Since you have experience in eCommerce, this must be familiar with you.

For example:
1. Understand the market. Is there a market for your brand? I.e. is there a potential buyer who would be interested in buying your brand? What marketplaces have you looked into to buy and sell these brands/websites/companies?
2. Pricing/valuation. How do you value your business? What valuation methodology do you use? is it a multiply of revenue, profit, or something else? Going backward, what kind of financials do you have to achieve to be able to sell your brand at the valuation you are expecting?
3. Fulfillment/transfer of ownership. How do you manage this? Is your business transfer-ready (i.e. having a system in place that can easily transferable to a new owner?)
