The verdict in three sentences
For a Chicago guarding company selling to property managers and corporate campuses, LinkedIn Ads plus email follow ups can win annual contracts at a cost per signed contract of roughly $6,000 to $18,000 (2026 market ballpark), for contracts worth $150,000 to $600,000 a year. The example below follows a fictional company, built as an illustration and never presented as a real client. The number that decides whether to keep going is cost per contract, not cost per lead.
The starting point
Our illustrative company employs around 250 licensed officers across Chicagoland and offers standing guards, mobile patrols and concierge security. Its VP of sales, Marcus, relied on referrals and RFP portals: one or two new contracts a quarter, with sales cycles of 2 to 5 months. Targets: property managers of Class A offices in the Loop and River North, facilities directors of suburban corporate campuses and security managers at logistics parks near O'Hare.
| Baseline metric | 3 month value | Notes |
|---|---|---|
| Sales meetings | 9 | Referrals and RFPs only |
| Contracts signed | 1 | Annual value $210,000 |
| Marketing spend | $0 | Brochure and trade association dues |
| Average time to sign | 4 months | Procurement and insurance review |
| Meeting to contract rate | 11% | Many RFPs decided on price alone |
Budget and market benchmarks
Marcus hired an agency for 3 months, with an email sequence sent to LinkedIn leads and to a list of 600 facilities and property contacts the company already knew.
| Monthly line | 2026 market ballpark | Choice made |
|---|---|---|
| LinkedIn media spend | $6,000 to $15,000 | $10,000 |
| Campaign management | $2,000 to $4,000 | $3,000 |
| Email tool and sequence copywriting | $400 to $1,200 | $1,000 |
| Monthly total | $8,400 to $20,200 | $14,000 |
| 3 month total | $25,200 to $60,600 | $42,000 |
Messages tested: officer screening and supervision, response time for mobile patrols, incident reporting through a client portal and transition support when replacing an incumbent provider. The Lead Gen Form asked for property type and number of posts. Email sequences followed CAN SPAM basics: clear sender, physical address and a working opt out.
Results after 3 months
| Funnel stage | 2026 market ballpark | Illustrative result |
|---|---|---|
| Leads from LinkedIn and email | 80 to 250 | 160 |
| Qualified leads (real site, real need) | 40% to 60% | 78 |
| Site walks and meetings | 15 to 40 | 28 |
| Proposals sent | 8 to 20 | 14 |
| Contracts signed | 2 to 6 | 4 |
| Cost per signed contract | $6,000 to $18,000 | $10,500 |
The 4 contracts: a Class A office tower at $320,000 a year, a corporate campus at $260,000, a logistics park at $180,000 and a medical office building at $150,000. Total: $910,000 in annual revenue.

Mini case study
Illustrative profitability check: at a net margin of about 9% on guarding contracts, $910,000 a year yields about $81,900 of margin. Against $42,000 invested, Marcus sees roughly 1.95 to 1 in year one, before renewals, which in this sector often run three years or more. Cost per lead, about $263, would have looked expensive in isolation; cost per contract at $10,500 is the figure that justified extending the programme for 6 months.
FAQ
Do property managers in Chicago really respond to LinkedIn Ads?
Yes, facilities and property decision makers are active on LinkedIn, especially at larger management firms. With $10,000 a month in media, the example reaches several thousand targeted decision makers over 3 months.
Why add email to LinkedIn?
Most leads do not book a meeting at first touch. A sequence of 3 to 4 emails a week apart turned part of the 160 leads into 28 site walks.
How long until the first contract?
In the example, the first contract was signed in week 8, after a site walk and a proposal. Allow 6 to 16 weeks depending on the client's procurement process.
Which metric should we watch first?
Cost per signed contract, here $10,500, compared to annual contract value. Cost per lead is only a weekly steering metric for messages and targeting.
