GST Registration & Trade License Help

I run a small general store in Derabassi, near Ramgarh (Punjab). I already hold an MSME certificate, a PAN card and a business bank account, but I have very little practical knowledge of the next compliance steps.

What I need now is complete, hands-on support with:
• Registering the shop for GST and obtaining an active GSTIN.
• Securing the Trade License from the relevant local authority, including preparation, online filing, follow-ups and resolving any officer queries.
• Explaining, in simple language, the compliance requirements that follow—monthly/quarterly GST returns, record-keeping, invoice format, display rules and any routine renewals.

Deliverables I expect at project close:
1. PDF copies of the GST certificate and Trade License, ready for printing.
2. A brief, customised compliance checklist showing the key filing dates and documents I must maintain.
3. A quick call or chat session to walk me through the documents and answer final questions.

Please outline your previous experience with GST portal filings or Punjab municipal Trade Licences and let me know how soon you can start.
