I was wondering can anybody give me some ideas one where I can find some Madlib, MF Doom, Adult Swim type samples?
More than half the fun is sampling sounds. Search online for free sample packs, download samples, buy new gear like synthesizers or sound modules, buy sample CDs (I would advise against that actually, most CDs are crap and give you like 5 usable sounds per 50$) buy records (very good source of samples) and sample from there and everywhere. Heck sample yourself making noises and use FX to create new stuff. You can also scavenge youtube for sounds. There are a lot of people playing synthy stuff or instruments there and in many cases you can sample without the fear of being sued. :p
I know what you must be going through at the moment, as I have experienced the very same, but you need to get more creative than 'please give me some samples'.
From what I understand gear-wise, you might be into looking at going for a Kaossilator for synthy stuff on the cheap. Other gear that comes to mind are Electribes, Roland Grooveboxes (D-2 , MC-303 etc.) and so on.
When it comes to already chopped samples, you really don't want to rely on pre-made sample libraries too much, unless you go with stock sounds from actual hardware.
That reminds me, a software DAW like FL Studio, Reason or similar usually comes with a pretty big library of sounds. You can sample from there as well.
So yeah, you should start your journey, instead of begging for samples.
