I need to build backlinks for my website http://www.gehnabazaar.com and its 4 pages

1) http://www.gehnabazaar.com/gemstones/28/alexandrite.html
2) http://www.gehnabazaar.com/gemstones/29/amber.html
3) http://www.gehnabazaar.com/gemstones/57/amethyst.html
4) http://www.gehnabazaar.com/gemstones/30/aquamarine.html

Keywords that I am targeting at, are

1) alexandrite, alexandrite jewelry, alexandrite stones, natural alexandrite, genuine alexandrite, alexandrite gem stone, alexandrite month, natural alexandrite gems .....for page 1

2) amber, amber mala, baltic amber, amber gemstone, history of amber, copal, amber resin, amber stone, amber jewelry.....for page 2

3) amethyst, amethyst jewelry, amethyst birthstone, amethyst geode, amethyst crystal, amethyst facts, amethyst mines, amethyst crystals....for page 3

4) aquamarine, aquamarine jewelry, aquamarine gemstone, aquamarine facts, aquamarine gem, aquamarine birthstone, aquamarine history....for page 4

It is not that I would want top ranking in google for all the keywords, but majority of them, including the main keywords for each page resp. eg "alexandrite" for page 1.

keywords that I am targeting for my website main page ( www.gehnabazaar.com) are jewelry designing, jewelry schools , jewelry designing schools, jewelry designing institutes, gemological laboratories, gemologists, gemmologists, diamond graders, jewelry designers,

give a good reasonable quote as I need link building for whole site if this campaign is successful. Coders who have previously quoted can also quote as now I know exactly what the site needs.

Page wise quote is also welcome on trial basis.
