The single-page mistake
Listing every service on the homepage with a paragraph each seems efficient and satisfies nobody: too shallow for a buyer evaluating one service, and too diffuse to be the source for any question about a specific one.
One page per service, properly
Each service needs a page substantial enough to answer what it includes, what it costs, and how long it takes — the page a buyer can actually compare. That is not achievable in a homepage section.
A service without its own page is a service nobody can be recommended for.
The homepage routes, it doesn’t explain
Its job is one clear positioning statement and a fast route to the right service page. Trying to sell all five at once loses the buyer who came for one, which is a specific case of asking for too many things at once.
Navigation is the positioning
How the services are named and grouped in the menu is the shortest description of the company anyone reads — an org chart in the nav is a wasted opportunity when you sell several things.
Content should feed a specific service
Every article should belong to one service and link to it. That is how a library becomes commercial rather than decorative, and it is what internal linking is for.
Cross-sell after the answer, not before
Someone reading about one service may need another, but only once the first question is settled. Adjacent services belong at the end of the page, never competing with its primary action.
