Name of the company
The name of the company is Destra, which is an abbreviation of the name of the owner of the company; Dennis Stratermans. The name should be written with one capital (the D) of the whole name in capital. Depending on the logo design.
Besides the name, there should be three words added to the logo. These three words makes it clear which services the company provides. The three words that should be added (as a sort of pay-off) are "Service, Beheer & Onderhoud". (Service = Service, Beheer = Management, Onderhoud = Maintenance). There's only one way of writting it (with comma and &): Service, Beheer & Onderhoud
The logo should be readable.
The pay-off "Service, Beheer & Onderhoud" should be visible / part of the design but it must be possible to use the logo without this pay-off.
No retro-font. No font with curly / fancy things. Modern readable font which is robust / strong.
Fresh retro-colours (like the old Italian Vespa colours). Two or three colours should be great (Search in Google Images on "retro vespa colours". The logo should represent a fresh, new company with an unique approach / working method: blue/green-ich colour with wood-colour. Optional to put the "De" in Destra in one colour and the "stra" in another colour (like FedEx).
Should it only be a font logo? No, if you can make a nice metaphor or real logo / icon that would be great. Maybe three icons which represent the three working area's. Or just one. It can be interwoven with the name of letters of the name or freestanding. That's up to you.
