https://www.serverhunter.com/ and
https://en.metadedi.net/ are useful resources for that. Though search for more information before signing up for anything expensive and/or long term as there are some truly crap hosts out there. There are some pretty good budget hosts in the mix though.
If you can wait until the end of the month you might find black friday offers from some providers. They usually get discussed in places like https://www.lowendtalk.com/ (I'm not sure how quickly such short term offers are reflected on the above server search sites, if at all). Again, do research on the hosts you chose lest you buy a lemon.
