Web UX: what are the practices of content segmentation without sub-menus?

I am thinking on the following task:

I have a document with the content for the web-site. Document is structured with Level 1 headers. Under each header there is relevant content. One of the top level headers - "Services". Its' content has three Level 2 headers:

  • "For Startups",
  • "For Enterprise",
  • "For Venture Capital Investors".

Each of these Level 2 headers filled in with text.

The problem:

I want to avoid sub-menus. Only top-level menu that will include Level 1 headers from the content document. At the same time I want to show "For Startups", "For Enterprise", "For Investors" (at least these names) on the top of the "Services" page so the user will embrace that there are three kinds of services without scrolling down the page.

The question:

What are the known practices of achieving sub-menu effect without actually using sub-menus?
