ICO will not work anymore if you are going to launch an ICO your chances is very slim, it's better to do an IEO, and be reminded that investors do not want to invest on project where developers are run by anonymous people, be sure to have your own white paper show who you all are and your capability to run your project.
I'm a programmer and have experience modifying the monero codebase.
I've had this idea that I want to make some minimal changes to monero to make it proof of stake. The changes will be kept minimal so that it could be kept up to date with any enhancements to monero, and adding ledger etc support should be easy.
