Client wants to use twitter, were to start?

I have a client in the commercial real estate industry and he is wanting to use more of twitter. I have him on the 1st page of google for many of his search terms but he is still not getting phone calls.

I want to venture into twitter and linkedin but I have very limited experience with this.

What would you do if you had a commercial real estate agent that wanted more leads from twitter and linkedin?

First build a legitimate account for the client. Full profile, area specific background image and link back to their site.

Start following the followers of existing accounts in the area. You can do it manually at first and then use something like Tweet Attacks slowly after you have a foundation. Then start tweeting listings and pics a few times a day.

If you want to be more aggressive, then you can build satellite accounts that also follow area specific users and retweet your clients tweets, but that might backfire, since you want to actually build a relationship with the prospective clients not spam them to death.

thanks mcgoohan6 for the valuable feedback.

My client already has a semi active twitter profile but it is generic and not name specific for him. it is location_realestate. Should he start a new one with branding his name?

I am going to start following followers of existing accounts in the area.

any thoughts for linkedin? he already has a pretty active group and leads it. any other tips for linked in?
