Hi,
I am a senior full stack web developer with over 10 years of experience.
We will have a meeting after accepting my bid and you will present how you are doing it manually. So I will be able to understand the requirement and then I will try to make a solution for automation. After that I will implement a trial and you will provide your feedback. Finally I will wrap all things together and it will be done.
I estimated it as 10~15 days task because I have a full time job and cannot work on it for full-time.
Best Regards,
Rassoul
