It doesn't hurt to have a facebook (or any social network) site but its definitely not free.
First expense is the time involved. Would your time be better spent meeting with builders and interior designers? Whats it costing you to operate the facebook site? Are you or your wife handling it? An employee? Would any of your time be spent better somewhere else?
Second expense is the fact that you give up ownership once you upload it. Your content will be used for ads and you will not receive compensation. IMO this is fine because they trade you for access to a built platform that reaches millions before you even sign up.
Another thing to think about is that if you invest a ton of time into facebook... and it joins myspace in the loser circle because of Google+ or whatever new social network pops up... you cant get that time back and you cant easily transfer it to the next platform.
Different companies have different needs. Fiascos bar NEEDS a facebook account because its great at reaching circles of friends who want to meet up some place and drink/eat/be merry. People make instant decisions about where they end up for food and drink and facebook is how many people communicate with each other today.
I use facebook to spam template sales. Without fail i make sale every single time i post something at facebook. It puts the product in front of new people. Should you have one? Yes i think so. Should you invest a lot of time in it? Depends. I think your dot com... yourwebsite.com is and always will be your most important asset. This is something you can customize and tailor and you own it forever.
I think social networking should be used to drive traffic to your main website. I dont think it should be used as a website replacement. Your facebook gallery should never have more/better photos than your website gallery. Your facebook posts should be used to direct traffic back to your site for special offers.
Invest the bulk of your time optimizing your website. Im not just talking about making it search engine friendly. Refine the "message" by eliminating confusion like multiple navigation bars at the top and bottom and on the sides. Put long winded speeches about products in a blog not on your websites home page. Replace old photos with new higher quality photos of current products. Have friends family and clients offer feedback about it. Make your dot com easy to browse and make sure it has just enough of the information so that clients can...

I have 2 facebook pages and both have under 100 followers. These are all real people... most are part of our industry. I don't think there are 3000 people in the whole world interested in following either page. If i ever have that many fans i think most will be useless contacts.
