another idea without fiverr??
maybe it's easier w/o using any of those tools just your $250
here's one idea: invest your $250 in CL PVAs and email accounts or maybe it's even better hiring a freelancer who can post for you (obviously finding the right person will be the hardest part) and your "only" task will be converting the leads into money, you can promote almost anything you can think of: affiliate products (CB, Amazon, dating offers) or CPA (email submits, trial offers) after checking if CL promotion is allowed or not
you should also pay attention most of these networks pay NET30 to regular publishers who doesn't earn them a few thousands per week
i can be wrong with this, but maybe not SEOing is the best way to turn your $250 into $1,000 in just a month especially if you need to start everything from scratch, i don't say it cannot be done, but it won't be easy for somebody who is a newbie in IM, unless if you're not extremely lucky
but you don't even need to put everything on one project
you can post fiverr gigs, it costs you nothing, so why not trying it at least?
spend ~$50 to a micro niche site, you already have the tools, so i guess, it can be done with that kind of money, maybe with even less ($30 or so), disclaimer: i'm not a SEO guy
and do the CL thing with the rest of your money
