Build a module for Prestashop

Hi, I'm looking for a developer which can solve bugs on the module I developed. I will send all the modifications you have to do: 1) I saw on prestashop that we can send a mail to customer to tell them they choose the delivery. Can you add this to the module, i have to provide you the template, please tell me how you want to proceed. 2) when you click on another delivery carrier and after on my module it doesnt close the first module 3) bug: when you choose another carrier and after mine it keeps the adress of the other carrier, /i suppose it s because they overwrite their adress, when they click on my module we have to overwrite with the adress given on prestashop 4) change name of fields in my module -1- Batiment, digicode, étage ... -2- Personne à contacter -3- Télephone [this has to be a number only] -4- Autre Field 2 and 3 has to be mandatory Field 4 has to collect the informations entered in Field additional informations of prestashop, and paste it in the field 4, the user will be able to modify it. 5) Problem of status order: it changes to my status orger but after 5 minutes it is coming back to "preparation in process" 6) Adding prestashop translation I'm looking for a developer who can have a new look on what has been done. That's why, I need someone who can optimize the number of requests, and can code a simple module.
