The price of this ico script is extremely expensive however it has only one advantage if we give it a closer look; it discourages scams ico and give room for only legit ico otherwise no one shall be interested in buying an $11,000 script and not sure if he/she will make 5 btc at the end of the ico.
In a nutshell, OP should try to reconsider the price of this script.
We have teams who already are interested, and two purchased, it's meant as you said for serious projects with larger ICO and long-term goals. In life you get what you pay for.
