Most schools have a 'Job Center' or something similar that receives job descriptions that local employers are trying to fill -- some of it's for recent/soon to graduate folks, but they also tend to get summer and intern opportunities.

Failing that, look to whatever government offices are in the area -- Town/City/County/District/Province/whatever. Unfortunately, some of them may not offer paid internships, but it could give him experience. I work for a government agency in the US, and we have a more formal internship program (paid, but you'd have needed to get your resume in 2 months ago, as they all go into a pool, and we pick those who seem to have a compatible background for the work we're doing.) ... but I'm also a Town Commissioner, and I know we have various programming tasks that could be done, and if we had a good applicant, could probably squeeze some money out of our contracting budget.
