How to make beats with just two instruments at home?

ok i rap as a hobby i have the lyrics all writtin up. now all i need is a funkt beat b4 i post it on youtube. i dont have a dj set or a keyboared and this is my dads laptop so i wouldent advise software. all i have right now is a drum kit and soon getting a b guitar. but with an actuail rap song u will need a vairity of sounds. and pls dont say go to google and search rap instrumentals becuse how is that hip hop if your stealing someone else beat. and the beat need to be you and original. so what do i do. i dont want to buy a dj set becuse ive only got enough for the guitar and i want that more. so can i just by a cheap recorder and just make the beat homade with the drums and the b. i also have an electronic drum machine. so how can i wrap it all together to make something good.
