CA Needed for DSC and GST Assistance

I'm searching for a Chartered Accountant (CA) who can handle two crucial tasks. Firstly, I need assistance with the signing of Digital Signature Certificates (DSC) on my payment receipts. Secondly, I require help in paying the pending Goods and Services Tax (GST). Coming from a non-accounting background, my understanding of these processes is minimal, hence, I am looking for an individual with a strong command of the subject.
