To sum up your email: Hi, You've never met me before, but I like your company. I expect to get paid $115K to lead a team as a senior developer, but don't want to relocate in order to be with the team.
I feel this type of email should get a response; however, I'm not surprised no one hired you. I'm sorry none of these companies replied. If hiring is as tough as everyone says it is, they should at least be willing to followup - they might find a diamond in the rough that way.
80% of jobs are filled informally, especially senior positions. If you know someone on the team, or if the team knows of your work and respects it, you should be able to find a position faster.
