Hello Mrs Molloy,
Because money making for most expats doesn't come easy on the Algarve, people tend to carve out niches for themselves wherever possible. One such company is algarvefilms. com
Whether they are able to supply Mr Molloy with any freelance work is not for me to say, but could be worth a shot. Most videographers you see kicking about are using high end Sony stuff, pointed at pretty twenty-somethings pontificating about the merits of buying this holiday apartment or that retirement villa. That said, there are a lot of events going on virtually all year round and people may be prepared to sub the coverage locally.
Also, try touting yourselves around the likes of Vale de Lobo and Quinta do Lago. This is where a lot of the money lives and people do come over to do weddings etc.
As for you, try asking at Browns of Vilamoura, Barringtons (Vale de Lobo, again). Not sure what there is in Lagos, but there must be some health clubs about.
Also, I'm trying to launch an internet business at present and am looking at as many different sites as possible. Any chance you could PM me your web address?
Good Luck.
