2D and 3D lanscape designs incorporting our company equipment

I need a designer to create basic 3D designs to showcase our outdoor gym equipment in a variety of locations.
I have attached examples of the kind of thing we've used before, but open to suggestions. We also have additional examples of competitor work which has worked well.
Bids vary and as such in some cases we'll need just 1 design, in others we'll need 2/3 from different angles.
We have all the products in 3DS or MAX files.
