I have to call a potential client in about an hour, who wants to be optimized for a pretty good keyword relating to her profession, which is Law. The term is local and gets about 100 searches a month. I'm considering charging her 1.5k monthly for this, as she could stand to make 10x that. The only real competition only has 6 reviews, the others have none at all, so I'm assuming I could rank fairly easily for this. What do you guys usually charge for clients like this?
