Compile list of 800 verified gyms for mail marketing campaign

We need a list of 800 gyms in the US, with the following information: - Gym Name - Street Address - City, State, Zip Code - Phone # - Email - Website Domain The gyms will need to be Boxing/Martial Arts gyms and we will provide the breakdown that we need for the 800. MOST IMPORTANT: The data needs to be cleaned and verified. The website domains need to be verified to still be active. And the addresses for the gyms should be taken from the website. Once the list is provided to us, we will randomly test and verify the data to ensure that 95%+ are good addresses. If not, we will reject the list. So a simple data dump from some site will not be good enough. We are spending significant money to send mailings to these gyms and need them to actually exist.
