Seamstress for a day

My mom has mobility issues and it’s hard for her to get around.
She is a large lady and has purchased many clothes that need some simple alterations to make them viable for her.
I’m hoping to find someone willing to travel to her home and spend a few hours altering some of her stuff or at least taking the measurements and making the marks needed to make the alterations.
I’m willing to pay by the hour or by the day.
This is what I’d like to do for her for Christmas.
I’m not sure what the correct rate of pay would be…I’m sure you’ll tell me!
