Bear in mind that you will have to collect a lot of documentation and then your application will take time to process, so it's not going to happen all that quickly. As someone else has noted, you may discover from the documents that you are not eligible after all.
And you do need to get some confirmation in writing from the Bahamas authorities (or a lawyer in the Bahamas) that you will be allowed to keep your Bahamian citizenship, unless you don't mind losing it.
