there ar lot of tools to design primers, Eurofins has its own (https://www.eurofinsgenomics.eu/en/dna-rna-oligonucleotides/oligo-design-more.aspx), but you can test Primer Blast from the NCBI (https://www.ncbi.nlm.nih.gov/tools/primer-blast/index.cgi?LINK_LOC=BlastHome), but never forget to test them on UCSC (http://genome.ucsc.edu/cgi-bin/hgPcr).
