Price for customization

Hello.
I am using a php-script which shows custom registration fields on the account page of the frontend user complete with the data specified by the user during his registration.
The problem is that the fields cannot be edited and updated by the frontend user, despite of having them set as editable on the forms.
I am not familiar with php, but looking at this code I think that it needs a little tailoring to get the fields editable.

So my question is if you can give a price for having it tailored by you?
I can send you the php script of course.
Thanks,
DV
