Setup worldwide FBA store and ensure tax information is correct

When it comes to setting up a worldwide FBA store and ensuring my tax information is correct, I need expert help. I am located in France and although I have some knowledge of the process, I need some guidance and support to get the job done. I require the job to be completed within a timeframe of less than one month. If you are qualified to offer this type of service, please consider applying for my project. Thank you for your consideration.
