What is the specific goal of your project? To perform a de novo assembly, or to resequence for SNP identification/copy number variation compared to the reference genome?

If by "simple" you mean, with small amount of experience, then the simplest is to contract a company that specializes in doing this, to whom you can send DNA and get back sam or bam files that have the variation data within, which you can explore with (for example) samtools. Or, you can ask them to upload a custom track to the UCSC genome browser with your variant data to look at online depending on your available computer resources.
