New Resale Flat - Laying Data Points

Need help here... After reading so much about how most of the gurus here place data points around the house, i also would like to have it done in my new place. But i am not an IT guy so any advice from forumers would be greatly appreciated.

I am renovating my place. & would like to install data points around the house..

However, i am going to have 2 locations for my TV, 1 at a time of course. So when u get bored with one position, you can change the living area to the dining area etc. There wont be a feature wall, so its just a tv console.

Anyone care to advice how this can be done especially that i would like to have individual data points in all 4 rooms & 2 points at the living room which arethe proposed TV areas. Pls advise me on the set up so i can get my ID to lay the cables before the cementing & tiling. Thanks in advance.
