My kitchen has a similar layout, and I have the d/w to the left of the sink, the trash to the right, and next to that a corner cabinet with a LeMans pullout. But it depends on the dimensions which are hard to read on your plan.

It depends on the rest of the kitchen. Please post the whole plan.

A cabinet salesperson is not a KD they can only work with the software form that cabinet company . If you post a to scale floor plan of the whole kitchen showing windows doorways and all meaurements clearly marked you will get lots of free advice here. It is easier to use graph paper for to scale plans .

Yes, dishwasher should be left of sink. It should not be between the sink and stove; the trash should be.
