Frequently Asked Questions

A consulting business is one of the lowest-cost businesses to start — typically $3,000–$12,000 covering LLC formation, professional website, liability insurance, and working capital. If you're starting from a home office with existing computer equipment, you can launch for under $5,000.

Entry-level consultants charge $75–$150/hour; experienced specialists charge $200–$500/hour; elite strategy consultants charge $500–$1,000+/hour. Project fees range from $5,000 for small engagements to $50,000+ for complex strategy work. Price based on value and results, not cost.

Legally, no — you can consult as a sole proprietor. But an LLC protects personal assets if a client claims your advice caused losses. Most corporations require vendors to carry E&O insurance and provide a W-9, which works for both sole proprietors and LLCs.

Former employers, colleagues, and professional networks are the most reliable first-client sources. Let your LinkedIn network know you've launched. Attend industry conferences. Offer to speak at trade groups. Referrals from the first 2-3 clients typically sustain most new consulting practices.
