I'm able to be willing
First of all you shouldn't say able to be willing as that is a understatement in your campaign to get the job. Secondly it should be I understand and will take full responsibility look that up if your not familar with English. Don't put too many negatives in your passage as I may say you won't get the job. Trying to be helpful here I understand and will accept all criticisim as expected by the bb community.

Heading on the right path so far. Are you?
