I had similar issue of finding an ideal person ,until I talked to someone who walked me to a business audition, there are various ways of finding one,but you should consider paying a visit to a business school/University especially during business exhibition and auditions,here you will find more people not only with the required skills but also the knowledge of business oparation and management this will serve as a great deal ,if it does work consider looking for a partner from different backgrounds/are of specialization but with matching skills,or turn to online sites but specifically entrepreneurial ones they will be of help, Wish you all the best in your search
