What type of shotgun should i buy for shooting clays trap and double clays and game birds?

This is a difficult question - ask 10 people and you'll get 10 answers. For clay trap and double clays, it's hard to beat a quality over and under or a side by side 12 guage. For upland game birds, a solid pump or semi automatic from any number of manufacturers will work. If your budget allows only one shotgun, a 12 guage semi-auto that shoots a 2 3/4 shell will work for clays and most game birds. My personal preference is for the Remington 1100. They have been around for years and replacement parts are easy to find.
