Pricing at a glance

Inbox Attack

Model
Hybrid fixed-fee/project pricing plus monthly retainer options, with a la carte service pricing and paid 1:1 sessions. Specifically: one-off system builds and audits sold at flat fees, channel/package builds sold as fixed-price packages, and an ongoing 3-month managed engagement sold as a monthly retainer. Not performance-based; the site explicitly says they turn down commission-based projects and appointment-setting work.
Typical range
$145-$2,650 per fixed-price service or session

Revenue River

Model
Custom-quoted agency engagements, primarily project-based and hourly; third-party directories also indicate they work on retainer engagements. Public evidence points to a classic digital marketing / web development agency model rather than pay-per-lead or pay-per-appointment pricing.
Typical range
$150–$199 / hr
