Hi Alex,
You're not going to be able to create VM that exactly meets the specs given.
I'm assuming that the GPU is critical part of the requirement, so I think you should focus on that first. If my assumption is incorrect then please let me know.
There are a limited number of GPU types available in Azure. Please review article below and see if one of the GPUs (and associated CPU) will be acceptable for your user's workload:

Once you have an acceptable instance type picked out you can decide which size you need, whether you need Premium or Standard SSD, etc. Please note that you may need to request quota increase before you will be able to create the N-series VM your user needs.
