Dont know of any digital soul-based music websites. Do u have a credit card and Internet access?...if so, the world is yours. Since you're just sampling, look into getting a belt drive turntable (usually less expensive than their 'direct drive' DJ-friendly counterparts). eBay, mane.
Although there are no record stores near you, I'm POSITIVE there's an attic full of dusty records within 20 miles of you...no matter where u are.
Remember...the best producers didn't make excuses. If j-dilla could make some of the illest beats the early 90's ever heard by pressing record and stop on his tape deck, I'm sure you can invest in an inexpensive turntable and scrap together at least a few pieces of vinyl.
Much love.

Maybe Craigslist in hopes of finding the dusty attic full of records, btw.
