Hongkong is lovely, and everyone loves it. But this is not enough. The biggest problem for you and your BF should be working visa and the jobsearch. Even if you or you BF find an employer willing to hire your BF, it is not guaranteed that he will get a working visa to start working. Your BF or the employer have to explain to the immigration Department why your BF is needed in this job and why a local can not fill this position.
Computer Skills is, as someone else said before, not a rare gift in HK. Your BF must have at least some qualifications, which are not easily can be find in HK. Starting with some high degrees, then some foreign language besides english, and end with a high salary to satify the officials promising high tax payments.
