# Evaluation taking extremely long

I am trying to solve the following:

I realise that these are complex expressions, and it makes sense that Wolfram Mathematica / my computer is having a hard time, but I need to know if I am going to wait a few more hours or a few more years.

QUESTIONS:

Is there anyway I could get a ETA for when the evaluation will be done?

Do you have any suggestions to speed up the process?

Is there perhaps a strong VPS/ remote desktop service you can recommend that will be able to solve this faster?

I see Mathematica is only using 25% of my CPU, can i increase this?
