The proposed new username is acceptable. However, the other elements of the block still need to be addressed. You will not be unblocked until:
- you agree to avoid creating or directly editing articles related to your organisation (requested edits will still be permitted)
- you agree to abide by the Wikimedia Foundation's Terms of Use and disclose your paid relationship in accordance with the paid contributor policy
- you indicate what areas of Wikipedia you intend to edit in the future
If you have no interest in editing Wikipedia beyond writing about your organisation, then you will not be unblocked. If this is the case, I recommend you consider alternative outlets.
