Quick question about a baby naming

vicky7139

I am using Rabbi Cove to officiate our DD's baby naming ceremony in a few weeks.  I am Christian and my DH is Jewish.  I actually found his name through a really old tread while doing a search here.  I didn't want to jump onto that thread since it was so old but I wanted to know if anyone can reccomend how much monetarily to present to him after the ceremony is complete.  We are not members of a temple, which is why we went the route that we did.  (We are doing the naming for the sake of familial tradition mainly...)

 Any suggestions would be helpful!!
