Hello Ecomdan! I run small tourneys at my local Legion on a weekly basis so I have ome idea on how to get started.
First of all you're going to need ALOT of chips, especiall if you are going to be running tourneys and cash games. The games I run are between 15 and 30 players, tournys only and I purchased 5000 chips in denoms at 5, 25, 50, 100 and 500. This is enough to play a 50 player tourney with 3K starting stacks. These chips were custom hot-stamped with "RCL" (Royal Canadian LEgion) one one side and the denomination on the other. SInce we're a amall operation I only purchased one table, but I also have 3 fold out felt table toppers which work quite necely as they fold out of the way when not in use.
I don't know who you are expecting to run the games, but if it is to be you, you MUST have a good handle on the rules of poker in all the variations you are willing to spread. You will be faced with alot of questions and ulings and they HAVE to be fair and accurate. Many people have their own interpretations on rules from their own home games or local casinos
so you need to be on the ball. If you don't have a good understanding of the rules or are just not that good at dealing with stresful situations I suggest hiring someone who is, at least for a short while.
The total cost of my start-up was roughly $2500. This included chips, table and toppers, cards and a button/timer. I found all my gear at www.nolimitpokerstore.com (http://www.nolimitpokerstore.com), but there are many other places.
I have no experience on running cash games, except for the occasional home game in my living room, so I won't comment on what you might need for that, save for different chips for cash and tourneys.
I hope this helps a bit. Let me know if there's anything else I can do to help.
