I need help to study and work

Hello, my name is João, i'm from Brazil.

And as you know, Brazil is not dealing well with covid, at the beginning of last year my father discovered he has cancer and that and COVID made us lose a lot of money, nowadays he has his treatment, but I lost my job, my studies and my computer which was the way I worked, I worked with telemarketing, today I need a notebook, I don't know how much it costs for you, but for me it is 3000 reais, 550 dollars approximately, any help I will get thankful, with a notebook I will be able to go back to attend classes and recover my job since vacancies have reopened. Any help is a great help, mainly because of the overvaluation of your currency, with that amount I don't buy something incredible, but I buy something light to take to work in case it is necessary to do it outside the home and perfect for studying and working, thanks.
