Cost for a unilateral brow lift? I am in my 20s. (Photo)

I am not satisfied with my right eye. I have had a hard time finding an average cost of a brow lift for only one side. Is it less since it's only one brow? Or somehow more complicated causing it to be more money? I do not want botox or any other producer that is not permanate. To have to continually inject my eyebrow every couple of months for the rest of my life sounds terrible...and expensive. Thank you for your time and your advice.
