Potatoes, staggered crops and keeping price of growing low

Hi
If you want to stagger crops, 3 people in household, how often would you start up a new container to grow spuds?
If you wanted to maximize crops between earliest start/last possible harvest, are there any particular types/breeds you should switch between over the season? (prefer sweetish and not floury potatoes, was thinking of planting some I know I like from morrisons that are classed as "baking potatoes")
If you didn't want to just go to the garden centre and pay fortunes for bags of preprepared compost mixes and fertilizers (organic sis and newish largish garden with huge demands on purse to fill it) is there any organic/natural method of filling containers

Oh, last question. What light conditions do spuds need? The house stretches west to east, garden is north, east and south of it with 6ft panel fence. I wanted to place the containers on west and/or northern borders onto a 3-4ft soil border inside the fence line as that's near to the outside tap and fills a narrow border.

phew, thanks from a noob with plans

 

Hi czeshirecat,
I'm very much an amateur in the veg growing field but I have been growing a few spuds over the last few years as well as other veg purely because I love the fresh taste of a newly dug potato or carrot just plucked from the soil.
For the past few years I have tried Aran Pilot, Rocket, Charlotte and King Edwards in my relatively small raised beds devoted to veg growing. The most successful for me have been Aran Pilot and Charlotte both of which have a lovely texture and flavour and I have held back a few tubers of each wrapped in a paper bag inside a cool draw in the garage. I have planted them as late as August and I am currently digging a few delicious fresh new potatoes having worked through my small batch of stored (brown paper sack) spuds thanks to few tips on this site. Admittedly the crop isn't as good as the ones planted earlier but the only extra ingredient I have used to enrich my miserable chalky and flinty soil is my own garden compost together with loads of horse manure obtained at 50p a bag DIY at a local farm, messy job but worth it!
