Oh lord...
Before you look at finding a suitable location,
purchasing or most probably renting the said location,
Pricing and purchasing equipment,
Designing a solid plan,
Writing a solid business plan based on the solid plan,
Looking at the market,
Looking at competition,
Running through cashflows,
Looking at profit/loss,
Setting up business account,
Registering with HMR,
Purchasing Insurance/ liability,
Contacting dealers and manufacturers,
Setting up trade accounts,
Stocking up,
Initiating a rewarding advertising campaign,
worrying about actually getting customers in to cover your overheads...
Ask yourself:
1) Is it worth it just to get cheap paintball gear?
2) More importantly am I about to invest a lot of time and money that I will never see again?
3) And finally, am I the type of person who can make that work (a passion for something isnt always enough, business and hobbies rarely come hand in hand)
Think about it. Good luck if the answer is yes.
