A poor valuation doesn’t just cost you thousands—it can cost you millions $$$, along with wasted time and stress. I help searchers, private equity groups, and business owners value private small to midsize businesses for investment, partner buyouts, tax, and litigation purposes.
Unlike many finance freelancers on Upwork, I’ve personally invested in, operated, bought & sold, made and lost money on private acquisitions and investments. That real-world risk taught me the stakes of an inaccurate valuation. For the past 15 years, I’ve analyzed thousands of startups and small- and mid-sized businesses and have become certified across multiple SME appraisal and finance bodies.
I am certified by the National Association of Certified Valuators and Analysts (NACVA) and the International Society of Business Appraisers (ISBA). I follow a structured process that documents every step, explains conclusions, and ensures credibility.
Services Include:
🤝 Partner Buyouts - deliver certified, accurate and defensible valuations when an owner is considering selling to a business partner or related party.
📑 Business Acquisition Investment Review & LBO Analysis – get value of a private business you are considering acquiring or investing in.
🧾 Tax & Estate Valuation – independent certified business valuations for estate and gift tax reporting as required by the IRS.
⚖️ Litigation Valuation – lost profits and economic damage reports based on court-tested techniques that deliver accurate estimates of SME private business value.
🚀 Startup & Venture Capital Valuation – get an accurate and defensible pre-money value for your startup or investment.
📈 Strategic Planning – provides owners, leadership teams, and investors with a clear view of business value to guide growth strategies.
🚚 Equipment Valuation – Certified desktop appraisals for machinery, vehicles, and other equipment assets.
🧮 Quality of Earnings - assess the quality of reported EBITDA adjustments and discretionary earnings of the business
💵 Proof of Cash – our best defender against fraud and manipulation of financial statements
🔄 Working Capital – create accurate estimates for operating working capital needs and target PEG for negotiations.
💼 Acquisition CFO – support from post-acquisition accounting integration and cash flow forecasting.
Why Work With Me:
✔️ Authoritative knowledge: thousands of businesses analyzed
✔️ Certified across multiple Institutes (CVA®, BCA®, CMEA®, FMVA®, and more)
✔️ Proven structured process that documents every step for credibility
✔️ Deliver fast turnaround (24–48 hours) when deadlines are tight
✔️ Top Rated on Upwork with 100% job satisfaction rating
What Upwork Clients Say:
💬 “Josh is exceptional at what he does and provided the exact skills I needed for a potential business acquisition. Accountants might be able to review financials, but Josh knows exactly what to look for.
💬 "Josh is hands down one of the best consultants I’ve worked with on up work. He is perhaps the most professional person I’ve worked with, as well as the most talented business valuation expert I’ve ever worked with."
💬"Working with Josh has been one of the best decisions we've made. We're happy to recommend him to anyone looking to understand the value of their company."
About Me:
I’m Josh and 15 years ago when I got out of the military I wanted to buy a business. When I got the numbers from the business I wanted to buy, despite having a degree in finance, I could not come up with how they put the numbers together. I outsourced the analysis to different financial professionals but got conflicting information on the business’s value. The pressure mounted as I was about to put up a significant amount of my net worth, and I could not sleep. From that moment, I vowed to never be put in this position again and have been on a quest to know how these companies are valued. This past decade I’ve analyzed thousands of these businesses along with gaining multiple business appraisal institute certifications. To go along with my degrees and certifications, I have read over 400 books on private business valuation and transaction analysis.

✸ Certified Valuation Analyst (CVA)®
✸ Business Certified Appraiser (BCA)®
✸ Certified Machinery & Equipment Appraiser (CMEA)®
