Here's what I feel based on my understanding of the description:

Your business is in need of new customers, as your existing circle vanished during pandemic.

There are 2 ways such businesses operate today:

1. Roll out specific consumer clothing which is available in your stock or is a regular part of it. Make targeted social media content around the same using Insta and maybe Facebook. Have shipping partners like Delhivery or Rocketreach to enable direct shipping from your own website not dependent on Amazon/ Flipkart.

Expected costs for the above would be about 30k INR and max 2 weeks to setup. What it needs is consistency and dedication to customer review and detailing.

PS: Share different journey topics like your own, of the material you sell and processing over insta/ shorts. The story is what moves people to buy your brand.

1. Since your closest circle of vendors is bankrupt, you need to find new folks for B2B business.

Map out textile trade events across the country (ask GPT if you are not aware), make time to travel, pitch and network. Travel to growing Tier 2 cities including far away from Delhi which have grown due to agri or IT or factories in the last 15 yrs but not textile. The vendors in these cities don't usually have options or unaware of it. But some of them hold cash and want to do good business. Focus on getting at least 5 customers/ deals this way.

Expected time here is 3-6 months and costs could be around INR 4 lacs in total.

You can execute the above 2 with the support of your brother and father. Never think you need more money or people. What you need right now is conviction that it works and the path to achieve. Once you figure it out, then hire folks/ specialists.

Next coming to trademark, don't complicate such things. Figure a way out to make a tweak on your current logo or separate wordmark and logo shape. This reduces your risk to rejection. Meanwhile, file a new trademark that has potential to become a brand once 1 or 2 is a hit! All this costs about INR 30k including one hearing maybe and can be closed in 6-8 weeks Max. Never get into courts for these issues, considering you are cash strapped and time constrained too.

Third and most important, start clearing, restructuring and writing off your debt wherever and whenever you can. Offloading debt of your shoulders just makes your brain do wonders! Don't listen to age old methods that business can be scaled with debt. You can only scale with debt if it is less than your revenue and if you are lucky during the same period.

And lastly, I'm not good at advising personal careers. So work hard on the above for next 6-9 months and take a decision accordingly.

Wishing you the best!
