Seating Arrangement Software

How do I fit 100 people seated at tables (round or rectangular) in a room which is 12m x 6m?

I get engaged and desperately needed to accommodate 100 people for a luncheon. change of location is not an option.

I need to seat 100 people, and have a main table for me and my fiance to be.

I can not find the time or patience to download a planning table, etc.

*** Can any1 please develop something for me in proportion to the size of the room and table size ***

(I do not know the standard size of trestle tables - I know they only seat three on each side of the length and one at each end = total of 8 per table)

Help pls help!
