Tip: Proven revenue makes all the difference.
"Ideas are a dime a hundred dozen. Implementations are rare as rainbow unicorns."
We live in the Internet age, so run up your gross receipts to $10K-$100K/month, then list your site on Flippa for sale at a 10x gross multiple... In other words if your yearly profit is $100K, then list your business for sale at $1M.
It's unlikely your business will sell for this. If it does, take the money.
More likely potential investors will contact you.
