Recruitment is a very challenging job and for you to be considered for this role is a privilege considering that you don't have the experience.

Negotiating matters but experience in the line of work matters most. The offer is above average as their are Recruitment Assistant or even Recruitment Officers in big companies and/or recruitment agencies that are receiving less than your starting salary.

Take the job and surely you will love it. The pressure is there and so is the fulfillment.

Good Luck.
