I searched online and I cant find where I can buy it? theyre all for rentals.lets say I bought 4 of them will it be enough for a start.and should I need a permit for that?
      Answer1:you can try google or yahoo and type inflatables or inflatable manufacturing companies. See if that helps
      Answer2:Regardless of the type or number of jumbers or bounce houses you have, you may need a permit, if anything, a business license as you are collecting money from the government.Some other advice is to make sure that you purchase jumpers that are made for what you are doing. They must be commercial grade in order to last and to help prevent injuries reducing your liabilities. Ask the vendors with whom you talk about product liability insurance and etc to protect yourself
