hmm okay. 2nd important question, what method do you intend to use? As I see it there are 2 ways, first is by chucking your products into a light tent which I think is the simplest & direct way of getting acceptable images. Second is by actually learning product / table top lighting. Backdrop can just buy a white/grey A1 vanguard sheet from Art Friend.
Either way, you can use speedlights or IKEA continuous day-rated lights.
You definitely learn more technical skills via the second method, since it tests ingenuity etc etc since you are saying can't afford softboxes. And the light tent method basically provides a 360 softbox for you. Decision is yours.
A lot of the online shops in CS stock such kits, I think you should have a good browse there.
