@ Big Dave: Fantastic! I'd had a look at the Crossword Compiler website but I hadn't realised that you could post your puzzles online. I usually try to scrape by with free software wherever possible but for this I think I might have to make an exception! Thanks :)
@trevor: Lucky indeed! I'll be sure to post my efforts here once it's up and running.
