Each new sales funnel I created took between 6 to 8 weeks to create, on average.
I had a team of 5 full-time people including designers, programmers, and copywriters just to get one funnel live. We had to glue together about 13 different products just to create one sales funnel.
On average, our costs to get one funnel live were about $20,000, and then only about 1 out of 10 would actually recoup that money. It took a lot of time and money to find another winning funnel.
