Guides For Selling Digital Marketing?

Hey guys,

I was wondering if anyone knows of any good classes, guides, video series etc. etc. on selling digital marketing services/running a digital marketing agency.

Really, the only one I have seen that looks decent is Sam Oven's consulting blueprint. It also looks like it has been updated to consulting accelerator now. Unfortunately, I can't drop $2000 for it.

Anyone know of any other cheaper options?

Thanks
