Need Help funding Laptop for College use

I'm facing some family finance problems.

My father was jobless for 6 months and I've been working part time to cover up those 6 months, now he has found a stable job but the bills are still in debt , we can barely survive each month .

So I was hoping to get a laptop so that I can work on my college assignments and work online part-time.

I'm learning Film & Tv Production, so to edit better videos it's basic need is an i7 core laptop which are all quite expensive, so I needed some help to buy it.
