What would you like done?
Write a theme component to remove the “Name” field from /u/username/preferences/account so users cannot change it. The approach is given here.
When do you need it done?
Next week or two?
What is your budget, in $ USD that you can offer for this task?
Open to offers but I think this is an easy job for someone familiar with themes. Please PM me if you can do it. Thanks!
