how much it cost to rework this code?

I thought so just, that it walks about this file.
I supposed, that I will have to exchange the part of code here and there, I do not know only about which part of code only I have to improve

Hi
You have to edit file:
..com_booking / assets / css / general.css

it line 1036 answers for width of displayed text
I made so:
.head .description {
padding: 5px 10px;
width: 710px;
border - width: 1px 0 0;

I greet!
I need make following correction:
I have to reservation already finished object and I want to field "Prices" displayed before "Supplements"
How do to make this?
