Hi,
I won't be asking for money unless I won't do this project for you.
I have understood that you want me to make changes in CSS so that the product display changes from 3 products to 4 products per row.
Referring to my profile, you will get to know that I am an expert in such tasks. It will hardly take 2 hours for me to complete your task.
Please provide me with the following details to get started:-
1. Wordpress and cPanel details.
I don't need any upfront or milestones, first I will prove and once you are satisfied then I can talk for money.
Most importantly -- With in your budget.
Regards
Sarv
