Revenue for engineering consulting businesses in Illinois varies by size, but most SMB-scale targets in our database fall in the $1M to $15M annual revenue range. Serava.AI provides revenue estimates benchmarked from payroll data, OSM business data, and SBA loan records.

Key signals for a high-quality engineering consulting acquisition include: long owner tenure (15+ years operating the same business), stable recurring or repeat revenue, strong online ratings (4.0+ with 20+ reviews), an established local customer base, and a skilled technical workforce. Serava.AI's Acquisition Fit Score (0-100) weighs all of these factors and benchmarks each company against your specific buyer criteria.
Most engineering consulting business acquisitions happen off-market, before the owner ever contacts a broker. Serava.AI identifies succession-ready engineering consulting owners in Illinois using tenure signals, business age, and local market data. We then reach out directly on your behalf and arrange a warm introduction, giving you proprietary access before any competing buyer.
Engineering Consulting businesses in Illinois typically trade at 3x to 6x EBITDA, depending on revenue concentration, customer contracts, and owner dependency. A business with $2M revenue and 12% EBITDA margins ($240k EBITDA) would price between $720k and $1.44M. Businesses with recurring contracts, long owner tenure, and clean books command higher multiples.
Serava.AI aggregates business data from OpenStreetMap, Companies House (UK), SBA loan records, and OSM enrichment sources. Each company is scored 0-100 on acquisition fit using owner tenure, years in business, rating, review count, and estimated revenue. Scores above 80 represent high-priority outreach targets.
