Basic HR Functions / Policies Of A Chartered Accountanncy Firm

Hi all,
I am a new member to this wonderful site. I am working for a C.A. firm. Recently I have been entrusted with an opportunity to draft the Basic HR Policies for the firm by my Managing Partner. Our's is a Partnership firm of Chartered Accountants having branches at Chennai-Bangalore-Cochin. I have to draft the policy for the headoffice i.e. in Trivandrum. It is having a staff strength of 15 including the manager, partners sitting at headoffice, audit staff, administrative staff and article clerks. We dont have any HR Person as of now.
Kindly guide me how to draft the basic HR functions and policies for the C.A. firm.

Dear diva,
I am also in a similar position. i can share how I have started, though I am also facing a lot of problems.
1. firstly, prepare a master data of employees & document all personnel files properly.
2. Take hold on attendance system.
3. Prepare all the formats like offer letter, appointment letter, salary structure etc.
4. Keep communicating with the employees regarding the problems they are facing & try to identify the best possible solution.
5. discuss with the management on what would be the appraisal system that you can follow.
Please let me know if I have missed on any thing & if you have any suggestion for me as well.
Thanks
