Short term help, rent payment

Hi. I'm in a short term hole that I need to cover. I somehow missed two rent payments last year that neither me or landlord noticed. I owe £1050.

I have a part term job that fits around childcare requirements, that pays £230 a week. I am training as a deep tissue massage therapist, exams passed with just coursework to go. I can charge £50 per her for this, and have been doing a couple of clients per week cash in hand.

I am on universal credit which gives me around £400 a month. I missed a review requiring me to upload proof of housing costs and this month I have found my payment was stopped, I owe rent today. So my total owed is 1500.

I have some cash in hand bar work through summer, sporadic weekend dates paying about £130 per shift and in June I have work at festival as a production manager paying £3000.

So I'm not in an insurmountable problem, but I need to pay my rent TODAY. Delaying is not an option. I need £525. What are my options
