I have only been in a game center once. It was in another state and I was surprised at how busy it was, but how poorly set up it was. Two collage ITT Tech guys started two up. One North of Indianapolis and one south, which was in Greenwood, IN. I went to the one in Greenwood. They used mostly old tube tvs for the consoles. I do not remember any newer consoles than ps2 and xbox. They had one wii, which was in a separate room. It solely played mario cart the old guy that worked there told me. There were a few pcs maybe 10, but the rest was tube tvs and consoles all over the place... in no uniform order. wires and cables were everywhere. So many were connected to orange extension cords, which draped the floors every which way. So easy for an accident.
I was not impressed with the setup at all. I saw great potential in the idea and dreamed of a well organized one some day. Several years later I found SALC. I have found everything I needed to learn on here through SALC and GCD before I finally made a decision that this is what I wanted to do. Since then I have written up a business plan and presented it to SCORE, which is good for small business start ups and for struggling small businesses. The one in my city said I was the third best prepared prospect business owner they have ever come into their building. They have high hopes for me in this business endeavor. ALl I need is the financial backing and I will be getting started on it.
Figure your system count... pc and console. Figure the sq. ft. you wish to start with with the amount of systems you have picked. Get a quote with help doing the stuff that you cannot do and for purchasing the stuff in bulk. Finally work up a business plan to present to SCORE in your area and they can assist you on the business aspect and how to present the business plan to a bank and personal investors. i am still getting quotes for other things that are more minor, but overall tweaking the business plan here and there is better than going into a bank and asking for a loan and not even having a professional looking business plan typed up. I presented it in a simple manella folder and SCORE loved how I did it. They let me keep it, but they said to be sure to leave it with all the banks and investors that you present it to. If you need to know the step by step process that I did to get the business plan then I can email it to you. Send me a personal message and I can send you the key headlines for what you want to have put in your business plan.
