What do you think about this proposal

It seems like an interesting concept, just so we are on the same page, we would give you 5 GPU and then you would in return generate 5-6$ a month would be approx 150$ a month minus 1$ a day for your work and effort would be 130$ take home?

Is the above correct from what I read?

Please also explain GPU as I am new to this area of expertise.
