Looking for product reminder module

Hi guys,

I am running an online pet store. when people buy pet food/ medication , I need to send them a reminder to buy the next one

I will add products to the module - if the product has option - i should be able to add two different time periods - for example 12 kg food bag will finish in 40 days and 6kg food bag will finish in 20 days.

People who buy the product will automatically receive an email when the time is up.

for example,, Hi there, it is a friendly reminder that it is time to buy food for your pet (pet name - which needs to grab when registering account) and here is the link to the product - link to the product page

email template can be edited.

Please tell me how much this will cost to build, Thank you
