Any Private Scholarships for students at a Government University in Sri Lanka

I got selected to UOM ITM, Kinda of dream of mine to go to UOM but I know the upcoming years I would need some help financially. I cant apply for mahapola or Bursary since the annual income of my family is above 500k I'm also doing a job until uni starts I'm saving that money to get a tab since my both phone and laptops are old but they functional. Is there any private scholarship funds I can apply
