Deploy Django app on Render (Problem with Staticfiles, WhiteNoise and CSS)

I'm looking for a freelancer to help me deploy a Django app on Render, so that it runs properly with staticfiles, Whitenoise and CSS. I'm not currently using any other hosting options (such as Heroku or AWS). I don't currently have a domain name registered, but I have created my Django app. I am specifically looking for someone who can add Whitenoise middleware, and set STATIC_URL in settings.py so that the deployment is a success. If I use "STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage' instead of STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' it works, but without the Staticfiles, so I don´t have my custom CSS file. And if I use STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' it gives me error, even if I change the Django version to 4.0.
So I need help just to set up this in the right way to have everything working.
