Oh...ok. I understand better. This helps.

Your are correct in knowing that you need to get them to engage. I do recommend custom tabs as a start, and most aren't really all that technical. You could use Pagemodo or Hyperarts templates. They are super easy to add to a facebook page, and both are very reasonable. Hyperarts is a good site for ideas on how to get more traffic. And...I still would highly recommend Mashable and Mari Smith as resources for ideas.
Meantime, I noticed on your website that you seem to be more of a generalist, than having a specific specialty. What you could consider doing is a theme of a month kind of posting. For instance, I notice you have travel listed. So, write a daily status update highlighting travel arrangement tips. You need to show your expertise. To get them to engage you have to invite them. For example you might say something like - "Recently I had a client who needed us to get them on a flight with only a day's notice! Not much time to get a good deal, but we were able to do...blah, blah, blah - and then ask them - what was your worst travel nightmare?" When they answer, you can tell them how you might have solved that for them.
You also need to ask them to share. You need to be a little assertive as well. Not aggressive or pushy, but assertive. For instance, I just put up a new page yesterday. My goal was to have my 25 in one day. I've gotten 23. I came on the forum here and asked people to like my page, and I liked them all back. Then everyone from this forum who liked me, I promoted them to my network. Then I pushed it out to all my friends on my profile, but I didn't stop there. As soon as the first 3 people liked my page (because at least some will) I made a post on my page thanking them for joining and I encouraged all the others AGAIN to go like my page. That got me several more. I have a goofy picture of a dog that I had, with a little story to go with it. I used that to promote some more, but people had to go to my page to see it. Go look and see how I did it. Oh...and while you're there...like my page.
The tips could go on and on. Having the reveal tab and a welcome page with video (if possible) and what is huge as well is having a freebie with an opt-in box. Make sure you are making them like the page before they get your freebie. Also, make sure you are writing blogs regularly and promoting them and always ask people to share. Make sure your information is in your signature line of your emails, and invite people to like & share. You have to just do it consistently and assertively everywhere you go.
Sorry that I'm rambling so much. I just get excited about it all.
