Installing CUDA, tensorflow properly on my laptop

Looking for someone who is experienced installing tensorflow and can do this remotely & quickly on my laptop.

I have:
- Ubuntu 20.04
- Geforce RXT 2080 Super with Max-Q Design
- Python 3.7
- I do NOT want the docker installation

I'm looking for a "fixed price" offer of around NIS 400. If you know what you're doing, it should take you about 15 minutes.

Currently, I'm getting this error message:
import tensorflow
2020-12-23 17:35:51.224158: W tensorflow/stream_executor/platform/default/dso_loader.cc:60] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory
2020-12-23 17:35:51.224173: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.

Basically, I need two things:
1. CUDA / tensorflow to be installed properly so that I don't get this error
2. A simple (text file) explanation of the steps taken, in case I need to repeat this in the future.

Thanks!
