Starting an HR department in my company, what kind of HR manager should I hire?

Should I only hire someone very experienced or someone with only 3-4 years of experience should be enough to start the team? What are your thoughts on this?
For some context, we are a leading online legal and regulatory education company with offices in Goa, Delhi and Kolkata. We are primarily looking for the HR to be based in Kolkata. Here is our corporate website: ipleaders.in. We have 27 people across all offices and even some people working remotely from home.
Looking for your advice on the same.

Dear Ramanuj,
As per your description it seems you have a less work force and based at multiple areas,operating off line also/remote also. But you look for a long term hiring solution is my suggestion.
You can always depend upon richly experienced personnel who can handle the core. And it also depends on your expectation from the person, if you want him/her to handle everything it is ideal to take a senior person having exposure in all traits/arenas.

Hi there,
I would suggest the following
Ist look for a person with professional qualification in line preferably with some work experience in same line.
Prefer who has exposure to local laws of the region and mainly person with working knowledge of local language, as he /she needs to liaison with outside government and non- government agencies and preferable to hire from region /state where the requirement is .
Year's of experience might depend on position being hired. Since, it is Manager, 6-8 experience in line , i feel is ideal.
If he /she is married and settled, the chances that they might stick to us for some time may be assured.
If he is given a laptop, he /she can work on-site , off-site and remotely too, as per jobs requirements.
Hope this helps.
thanks

Mr.Vamshi and ssrow gave good inputs. Don't look at the number in terms of experience but what matters is the level of exposure the candidate has in the same line of activity. Your establishment does not seems to need large work force and your HR profile seems basic and generalist in nature. The HR professional, as per the description of your business profile ( a greater detail would have been better), shall have fair exposure in recruitment of legal professionals, salary administration,statutory compliances of key employment laws like Shops and Establishments Act, PF,ESI (if applicable), Contract Labour Act etc. and skills in drafting, communications, analyzing, liaising etc. However it would serve you well to prepare a list of your HR needs so as to zero in on the candidate that fits the bill.

Dear Sir,
If I were in your position, I would do the following:
a) Hire a professional in HR with about 3 years' experience. Reason? For a small staff strength you don't need highly experienced person. Even if such a person was to be hired, it is unlikely that a good candidate would make himself available. Moreover, long experience would entail high remuneration. Such extra expenditure would not be warranted.
b) Occasionally the need for more experienced would be felt. To fill this void, I would seek services of an expert consultant on suitable terms. The consultant could visit the Company establishment once in a while and provide advice on phone/via email as and when required. This will ensure that no gaps will be left unplugged and the cost also would be reasonable
