Transfer website and email from one hosting service to another provider Office database securities- like restrictions on copying the data, erasing the data, sharing the data between the user etc Plus day to day troubles

I am looking for a freelancer to help transfer our website and email from our current provider to a new provider. We have already chosen the new provider and are looking to apply security restrictions, such as copying, erasing and sharing data between users. Additionally, you will be required to provide day to day troubleshooting and technical support if needed. Therefore, we need someone with a great deal of experience in this area who is reliable and trustworthy. Thank you for considering this project!
