Selling a bigger company? Bill Lange and Ken Oppeltz are Merger and Acquisition Master Intermediaries and routinely have sold larger companies to investors, other companies, and private equity groups.

We are a full service firm offering private business sales, mergers and acquisitions, and valuation services. Working with you, we determine the true earnings of your business. This allows us to value your business using the income, market (comparable sales), and asset approach. Once we have agreed upon the value, we will market your business using: *A comprehensive 33 step process to get your business sold for the highest possible price *A confidential business review. This comprehensive document sells your company by highlighting everything a buyer needs to know to make an informed and intelligent offer. *A digital interview with you and tour of your business. This allows purchasers the opportunity to understand your business without disrupting your employees and customers. *Confidential exposure to private individuals, companies, and private equity groups. Our company maintains the most complete database of these potential purchasers through ongoing memberships and subscriptions to proprietary databases. *Simply put, our company can reach more potential purchasers, which when coupled with our marketing materials, will produce more and better quality offers than anyone!

Experience and Professionalism Count! Only trust the sale of one of your biggest assets to someone that has actually done it, not just talked about it! Ken Oppeltz and Bill Lange, our managing pricipals have been involved with hundreds of transactions and have been actively involved with the California Association of Business Brokers and the International Business Brokers Association. Vanguard Resource Group only sells businesses--in fact, since our beginning in 1995, that's all we have ever done. Since that time, we have sold virtually every type of business. Although our "sweet spot" is businesses valued between $250k and $2MM, we have sold businesses with sales prices exceeding $27MM.

If you are interested in selling your business, we would like to speak with you! We encourage you to speak with multiple business intermediaries! We think this is the only way that you can truly appreciate the added value that comes from working with a professional intermediary.
