Any sport affiliate which involves horse racing, football, and cricket would be your best option. Rugby and tennis are also popular. I don't have any specific links for you though for specific sites, hopefully this is a good start!
Good luck!
I would go with something like blogger.com or such which is free. once you have a bunch of material then you can get a domain name and re-use the material to launch it. Just an idea!
buying selling links are no good (unless they have high traffic and are no follow). If google catches people buying links that persons site will be suspended for a year. see googles rules for webmasters for more details.
