tell me your keywords, I give price for top 5, bottom 5 in G,Y,MSN add all the top 5, bottom 5, together (thats total amount) half down, then half when rankings are achieved for 3 weeks
deliverables
monthly report, (links, on site optimization, off site optimization)
after getting positon the amount due would be the second half of total price, then if you wanted there would be a maintenance package of $x or $X /mo to keep gaining links and thus stay on top.
*if your rankings can't be achieved you get your 1/2 down back. - in this model also includes transparency of links and methods also education of client, no hold barred Q&A anytime phone call etc...
