Having taken a brief look at your web site, it appears you have a considerable opportunity. The recent acquisition of Getty Images, the world's largest picture agency, by the Carlyle Group for $2.1bn is indicative of how valuable your company's offer might become.
I would recommend visiting my company's web site: www.exportaction.com. We assist UK SMEs add sales, profits and value to their companies by assisting with the establishment, development and management of presence in US markets.
For less than the cost of a virtual, or box number, office, you can have a real office in the USA staffed by people who know about your company, its products and services and who care about your business.
If what we do is right for you, you can have a real USA office operational (with a company, attorney, accountant and bank account if you want them) in less than ten working days. Well you did say you wanted to get traction quickly.
Please fell free to get back to me for any additional information, or clarification you might want. We don't have sales executives and you won't be receiving interminable telephone calls and emails. Nor do we charge for an initial discussion.
As the world's largest, single-country market, the USA represents a huge opportunity. Most of the individual markets of the USA are between five and ten times bigger than their UK counterparts. By all means act quickly, but do it while paying careful attention to risk management by avoiding unnecessary capital expenditure, or entering into long-termm, inflexible contractual arrangements.
With kind regards and best wishes.
