My understanding is that blackberries have a big root system - not sure how happy it will be in a pot. Hopefully someone will be able to advise. Also hope you get a great harvest. Even in its first year I picked a few Kg!

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
Water generously but allow the compost’s surface to dry out before the next watering, without it becoming bone dry
Leave hardy fruit outdoors over winter
For most fruit, choose pots 50-60cm in diameter.
When planting, place plenty of crocks in the bottom of the clay containers to retain potting media during watering. Use a good-quality compost (John Innes No 3 is ideal), or multi-purpose compost mixed with one-third by volume grit or perlite. Incorporate controlled-release fertiliser pellets, or feed fortnightly with a high-potassium liquid tomato feed.
The best support for Blackberries would be vine eyes and wires.
I love Blackberry and Apple pie, so might have a go at this myself. No room in the ground, so a West facing spot by a wall in a pot will have to do. Too many choices and not enough ground!
If you use JI 3 (and I think that's the best option) I'd suggest adding about 15Kg of extra grit (in a 60cm pot). I don't think there are any brands of JI for sale now that follow the original mixture and I find that used by itself it drains quite poorly.
I wouldn't use multi-purpose compost (MPC) as it breaks down quite quickly. It's really only meant for raising seeds and growing them on. After 1 season or so it's pretty useless.

Thanks @Pete.8 That's what I thought, so thanks for confirming. I've used JI3 in several larger pots and always incorporate grit. Better too free draining than a quagmire!

PS - I'd be interested to see what they say for future reference
