Rather than go wired, why not use wireless radio triggers. Pocket Wizards are not the only things on the market. I use Yongnuo RF602 triggers and they are very reliable with a great range. Cost around £25 for a set.
Ok you won't have TTL control of flash, just manual, but it's better to learn how to light manually than rely on anything 'auto'.

This is a shoot I did using RF602's and a couple of cheap manual flashes (YN560's - around £60);
