Thanks for the reply. Here are the bits that we've already attached:
- Registration documents, tax-registration (Service Tax and GST) with a CA certificate and some of our contracts
- References from our clients with specifics about each project - not all clients but enough to cover each one of the 12-years so far
- Invoices raised for those clients, through PayPal - connected PayPal activity (invoices and payments) with corresponding activity on our bank account statements - to indicate connection
The self-affidavit is something that we are making at the moment, explaining the role and the relatively superficial nature of the organization.
We are providing a Letter of Explanation as well, explaining our business structure and the contractual nature of all our hirings. So all in all, Step 1 of what you mentioned is done and Steps 2 and 3 are the most common recommendations so looking to wrap that up today and cross my fingers!
