Pricing varies widely by scope, seniority of the team, and location. On Accellist you can filter by minimum project size and hourly rate. Typical engagements range from $5,000 for a focused project to $100,000+ for a multi-month retainer.
What does a Marketing & Advertising company do? +

Which industries do Marketing & Advertising specialize in? +

How do I choose the right Marketing & Advertising provider? +
Start by matching on fit (category + budget + timeline), then evaluate the short-listed agencies on three dimensions: (1) portfolio relevance to your industry, (2) verified client reviews — especially with similar project scope, and (3) response speed and quality when you send a brief.
What are red flags to watch for in a Marketing & Advertising? +
Watch for: no verified reviews, vague scope or pricing, contracts without clear deliverables, poor communication during the sales process, and reluctance to share references. Accellist verifies every listed agency, so these risks are minimized — but always ask for case studies and references.
What questions should I ask before hiring a Marketing & Advertising provider? +
Ask: How will you measure success? Who will be on my team day-to-day? Can you walk me through a similar project? What happens if scope changes? How do you handle confidentiality? How quickly can we start? Each of these uncovers a lot about the agency.
What’s the difference between hiring a Marketing & Advertising agency and a freelancer? +
Agencies bring a multidisciplinary team, process maturity, redundancy (someone is always available) and accountability. Freelancers are typically cheaper and more flexible but depend on a single person. For high-stakes or cross-discipline work, an agency is usually the safer bet.
How long does a typical Marketing & Advertising project take? +
Short focused engagements (audits, sprints, landing pages) run 2–6 weeks. Mid-scope builds or campaigns run 2–4 months. Ongoing retainers (growth marketing, product development, CRM) run 6 months and up. Each agency lists typical timelines on their profile.
