I'm looking at 2 options right now for payments. My business manages online ads so I can do the typical $1,000 for a website and then $1,000 recurring monthly for optimization and then ad management fees.
Or, a larger upfront fee such as $5,000 - $10,000 for a site and monthly optimization, as well as ad management (the ad management would be recurring). I know guys charging $20,000 to $30,000 a site just for LPO.
If you do LPO and have figured out a structure that works well for you and the client I'd love to hear your feedback.
