Hey there <Name, Surname>,
It was a pleasure working with you. I hope that we can have a chance to work together again on another project; you know that I am always available to join your team as needed.
At this time, I would like to ask you to provide me with a referral based on our work together. When you have the time, please just follow the link [link to form] and fill the form. It would mean the world to me.
Lastly, would it be okay if I use your name together with the referral? Please let me know.
Thank you so much.
Best regards,
