Relieving A Consultant

Hi,
Can anybody please help me with the below.
I have a consultant ( CXO level and an Indian ) working in my company from past 2 months and now he has resigned his role. As my company is start up, i do not have any template to give his relieving in letter. Can anyone please suggest with a template of a relieving letter for consultant (retainer).
Thanks for the support in advance.
Regards,
Swapna K

Hi
1) As he is a consultant then no relieving letter is mandatory.
2) Apart from that he just worked 2 months.
If still you are planning to give then you can mention as
Towhomsoever it may concern
This is to certify (Name) was engaged with our organisation for the period of (From Date & To Date) as (Designation)
You can add anything more if required
