CAD Drawing for 4x roller components

I need a freelancer to create a set of enginneering drawings for a roller design I have. The aim of these drawings is so that I can get the units manufactured. The design has 4 main components 1. A roller 2. A shaft 3. A link plate 4. A lifting bracket. For each component I need an isometric drawing with a front view, side view, top veiw and an isometric view. I would also like an exploded view drawing, showing how all components fit together (along with a bearing and split pin). I require the drawings in both a cad format and pdf I have a set of basic 2d drawings for each component that can be used to work from, I have attached an example below. The full set of drawings will be provided to the winning freelancer. Once the first set of drawings are completed I'll will then need at least another 4 sets for different sizes and am aiming to give these to the same freelancer
