StampT Equipment- oilfield equipment rentals - make what I attached better (designed by myself)

C'est ce que StampT Equipment- we envision the S and the T (first and last letter) larger font than the "tamp" in the middle. But all capitals? recherchait dans leur logo design

We need a logo design for a new oilfield/industrial equipment rental company 'StampT Equipment' . We see the final design as being something like a 'Stamp of Approval'.
We want to express confidence, easy to see, and easy to print as it will be placed on the side of equipment. We are leaning to colours that will stand out against a 'gentian blue RAL 5010' as equipment will be painted this colour.
Company values include integrity, good character, and hard work Voir plus
