Inbox Attack

Model: Hybrid fixed-fee/project pricing plus monthly retainer options, with a la carte service pricing and paid 1:1 sessions.

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
