Possibly late in the game here but I have just set up a Call of Cthulhu game myself and am accepting character submissions. Some things to note.
1. It is adult and will contain adult content.
2. It uses those 'crunchy' 7e rules you've all been talking about.
3. It uses a heavily modified published scenario and sourcebook.
4. Its set in modern day Japan (but most investigators will be British).
