  <div id="content_0" class="content">
    <h1>Provide Success Stories</h1>
    <p>Give Overview Presentation</p>
<ul>
  <li>It is a typical government contract</li>
  <li>It is competitive and I have to "beat someone else out"</li>
  <li>I don't have a chance against the big government contractors</li>
</ul>
<p>Other promotional strategies could include:</p>
<ul>
  <li>Conversations with current/past award winners</li>

<h2>Training Classes</h2>
<p>Search "SBIR Training", "SBIR Conferences", "SBIR Calendar" or "SBIR and name of an agency i.e. USDA, Navy, Army, etc" Some SBIR consultants give training classes from time to time as a way to solicit clients.</p>
