I could post the usual rules, but I expect a decent SEO/link sourcer will tacitly understand them and I will trust somebody to do a good job as this is potentially the first job of many. If you can do a good job and get me 10 PR3 or 4 one way links for $50 (this is the fixed budget) then I have literally thousands more links I need at $5 per link (one way, PR3+).
This website concerns the selling of sporting and pop concert tickets. Can you find 10 PR3 or PR4 one way links that are themed to this topic?
