Hello Sir/Maddam.
I would love to work on this job for you.
First I would need to confirm that this form is intended to be displayed on a website (as apposed to a mobile app or other software). If so, the steps I'd need to take in order to understand your requirements and deliver on this project would be:
1. Find out what back-end you are using and where the required fields exist in your database
2. Discuss what you mean by 'signature pad', and
3. Discuss what cloud server is best to store images for your requirements.
Let me know if you would like to me to do this job for you.
I am a native English speaker and university-educated web developer.
I assure you, you won't regret it.
Kind Regards,
Christopher R Dodd
