But being as I just bought my home and an engagement ring for my fiance, I would only have around $1500 to invest and am pretty cash poor.

I loved Floridas Best Real Estate School near the Florida mall.. they guy was engaging, funny, easy to understand.. they teach the class based on the state exam, NOT the class exam (big difference).. $300 is pretty reasonable.

Also in very low income areas I often rent $500/mo apartments to people who earn social security disability of $721.

Also, I've developed relatively sophisticated referral-based selling strategies that that require me to educate the referral sources and show them both to how manage the client's expectation(s) and more recently, very specific ways they are to refer the client.So, I utilize offline and online advertising and, obviously, give a lot of thought to each and how they fit in the overall marketing mix.I like direct mail, inbound telemarketing, well-placed, industry/profession specific print ads, direct mail, paper & ink newsletters, public speaking, press releases, blogging & forums (limited social media), direct sales (in person), some conferences and specialty advertising (mugs, pens notepads) and a few others I won't mention.
