I am going to jump in here and add my sentiments that in your present situation pigs are definitely a no no. It would not be practical and would not be humane.
Without sounding condescending Geeza, I really urge you to do some research on both pigs and chooks. There is a lot of really good information on here that can give you a good incite into both pig keeping and keeping chickens. You sound very enthusiastic and that is great, but ultimately you are talking about taking responsibility for living breathing animals, and it is not a responsibility to be taken lightly. Is it possible for you to visit a smallholding where they keep pigs and chickens? This might give you a better understanding of both of their needs. Also there are some very good websites on the net - The Pig Site being one, pigsinfrance another. Just Google caring for pigs, starting with pigs, there will be loads of info available.
If you go the route of renting land somewhere, then you have to consider the costs involved to provide adequate fencing and housing and security. If you have Houdini pigs that want to escape you will be in trouble if you are not there on the spot. There is a lot of thought and preparation involved.
Another option might be to take the route of buying a couple of weaner's, or even one, and let the breeder raise them/it for you with their other pigs. If you can find someone nearby, you could get involved with feeding and cleaning duties, and really get to know your pig/s, thus still having the experience. Or, team up with someone with more land, and buy and raise them between you.
There could be a way if you consider some other options, but in your situation, it just couldn't work with pigs.
What ever you decide, it is really important to learn as much about the caring side of the animal. Their wants and needs, their habits, medical needs, social groups, feed, housing, bedding, to name but a few. Once you have done your research, you will get a better understanding of why the contributors on your posting advise against your plan.
Good luck and please keep us up to date with what you decide.
