Hey There,
Greetings!!
May I please request you the URL to your present Prestashop website. So that we can review the same and acquire all the required understandings to move forward with this work.
Adding to this, It would be great if you can provide me out with a list of all the feature changes you are looking for. Once all the changes/requirements have been well communicated with us, we would be able to provide you with our estimation for the work.
***If required, we can sync up over Skype and discuss further in detail.
Regards,
Ibrahim Adil
