Correct the text on the website in Spanish.

I am looking for a person who knows Spanish well and can review the website in Spanish. So that all the text is harmonious and understandable for a native Spanish speaker. 
I am attaching the link to the website for understanding the volume of text:

Please write the cost of your work per hour online.

I see the work this way: We will have a call on Google Meet and go through the screen correcting errors chronologically.
It needs to be done today - tomorrow
