Pricing at a glance

Marketing Signals

Model
Custom-quoted digital marketing engagements, most plausibly sold as project-based and/or retainer-style agency services rather than a fixed self-serve plan. Public evidence shows PPC, SEO, digital PR, integrated search/SEM, lead generation, and analytics reporting; the agency’s own site repeatedly pushes buyers to “get in touch,” while third-party directories list minimum project budgets and hourly rate bands.
Typical range
$150 - $199 / hr

Single Grain

Model
Custom monthly retainer / revenue-marketing engagement. Public evidence on Single Grain’s own site says engagements start at a monthly retainer, and directory profiles indicate they also take project-based work with custom scoping rather than fixed packages.
Typical range
$15,000+ / month
