As a veteran of 7 moves in 8 years, if you can at all afford it, get the pros in, especially with a little one in the mix; the stress will be so much less. If you've got more than one van-load, proper removers might be surprisingly competitive, as petrol and ferries will all add up. Worth getting quotes from local removers at each end of the journey; if you can be flexible about exact times you can sometimes get someone's return load cheap. I've used both van hire, blokes and a van, and proper removers in the past. The proper removers have all been great, DIY has been a pain but manageable with not too much stuff, and blokes with a van have been 50/50 good/fucking awful - for that option I'd now only use ones I had a personal recommendation for.
