Thank you for inquiry. I appreciate the oppotunity to assist you.
1. that's correct, for development purpose, you may need to buy golden package.
2. when the client apply for a direct hosting contract with 123flashchat, if they purchase the license together, they can have more cheaper price on the hosting service. you may check this page to get the pricing details and compare the price to buyer and to non-buyer to get a better understanding:
http://www.123flashchat.com/host-price-table.html.
And later on when they change their mind, they can also host chat by themselves as they already obtained the license. are we clear?
To purchase the license and the hosting together,
you can visit the bottom of this page:
http://www.123flashchat.com/buy.html
check one license, then check "I need your chat hosting serivce ",
click "Next Step" button, and you will see the total price.
good luck and hope we can do business in a long run!
