First time benefits claim questions

Hi,

I am a PhD student in the final stages of writing up, however my scholarship is about to run out.
I will convert my study to part time at that point. I don't need much more time for writing, however I will be waiting for corrections from my supervisor.

I am actively looking for jobs (engineering). I have applied to 120 so far in the last 3 months, with responses such as 'under qualified' for a graduate job that I have studied and have work experience for.

I have good engineering skills and see a market for a few of my designs and considering self employment. However I was wondering if I would be eligible for JSA and other benefits if I'm self employed, and not making money...as I am starting up. I have very little money to support me. All I have right now is the stuff I have learnt over the years.

I have looked at the the .gov website as well as the entitlement websites.

Any advice is appreciated. I had never contemplated that I will need to apply for unemployment benefits and know nothing about it.

Many thanks
