Starting a business by buying rights to a Clickbank product

I've been mulling over the idea of working with Clickbank sites for a few days now and after putting pen to paper, I've decided that I'd like to invest seriously in site flipping: time, money and effort. I'm not incredibly short on any of the three but there definitely seems to be some dispute over what constitutes a big budget on this forum. $1000 is pretty considerable for me so I want to make the right moves and plan everything as far as possible to minimise risk.

My plan
I want to purchase a CB site that is in decline or has been poorly marketed. Budget will be $1000 and a further $1000 to market and build the business. I'll reinvest all profits into the business to increase growth as much as possible.

My target site

• Niche must be one that I enjoy as this will make it easier to work on.
• Niche keyword CPC must indicate that there are easily-accessed prospective buyers for my products.
• CB gravity should be 0-2 (2 is poor enough that I can negotiate a good price, above 0 means they have had affiliate sales in the past 8 weeks)
• Niche must allow me to introduce a range of physical products to sell (solar panels, sports equipment etc)
• Products should sell for about $150 (good figure to work with as you don't need to shift tonnes of stock to hit target profits)
• Site must be getting 1000 uniques/month (plan to pay for at least some of my traffic anyway so this is less important)

Tactical plan
The aim is to purchase a poor-performing CB site by negotiating down and making the owner glad that they are getting anything for it. Hopefully this will mean a site doing $100-$250/month for no more than $1000. I'm hoping to boost this figure up to $1000/month in about 6 months, feeding profits back into the site. I'll then work my magic and sell a site complete with stats showing continual growth for at least 12x monthly profits which should hopefully be about $12,000 by that stage.

Does this seem realistic? I'm planning on shortlisting sites this week. Basically, I just want to think through my moves and plan as much in advance as normally I jump in with 2 feet, waste time and money and end up getting burnt out and disappointed by poor results.
