Guidance needed for registration of a religious PUBLIC CHARITABLE TRUST & availing tax exemptions

I need to register a PUBLIC CHARITABLE TRUST (religious objective) and I would like to get tax exemptions (income tax & GST) for its income.

Do I need to consult any professional to help me with the above-mentioned work? If yes, then what category of professionals would be most helpful for my work? CA or CS or Lawyer?

I'm a complete novice and I don't have any idea about the registration and other legal formalities related to Public Charitable Trusts

Can anyone provide a sample trust deed for religious Public Charitable Trust?

Can anyone guide me through the steps to be followed for applying for the registration for a religious Public Charitable Trust in Ahmedabad (Gujarat) and also through the taxation and other legal compliances, please?

I would truly appreciate the support from professionals on this platform
