Gardening advice planting some bushes


Hello! I wonder if someone could help me.
My house does not have a garden, however it does have a flowerbed at the very front, which is 300cm x 40cm.
It previously had a manner of random out of control bushes in, some of which were very thorny, so I removed the whole lot and my plan was to put a nice row of plants in.
I spent a while thinking about it and I think I would like to put in Euonymus Fortunei emerald gold. I have never done any gardening before. My plan was to buy some compost and put an inch of it down, then dig and plant a row of these.
Do you think that would work? I found two places online that sell them, the price seems wildly different though, one place is charging £8.99/each (15-25cm) and another is charging £2.35/each (10-15cm pot grown).
It recommends to build a hedge wall to plant 10 of them 30cm apart. I suppose I would like a little hedge wall but it doesn't have to be crazy thick, I just want it to look kind of nice. Plus if I bought 10 @ 30cm apart as it suggested the end two would be right against the side of the bed which doesn't seem right - probably 8 would make more sense, if not less.
Also I worry that planting little 10cm big plants that they might just die cos they're tiny! Also I'd have to stop weeds growing, after I dug out all the other stuff it filled up with weeds very quickly. Are you supposed to let them grow in the pots a bit more first before planting them outside?
I guess I would put wood chips or something down to block the weeds until they are grown.
Any advice is welcome. Many thanks. If there's a better board or place to ask a gardening question please let me know or move/remove my question.

20-25cm pots are a better size, in my opinion, agree that 10-15 is too small and you'd definitely need to bring them on for too long before planting them into the ground.
Pot size determines price, generally, so before purchasing, do some searches/shop around because different outlets have different price bands per pot size and cheaper rarely equates to an overall better deal.
(I drive past a house, daily, where Buxus hedging has been planted in that small size and within the 3 months they've been down they're already weed-ridden, some upended by birds, and not thriving).
Euonymus is a good choice, nice and hardy, and an attractive hedge.
The compost idea though - did you mean lay it down ontop of the soil and plant into that ?
I will see if I can find somewhere selling 20-25cm pots, do you think at that size I can put them into the ground?
I'd say if you can find the larger plants in a garden centre or nursery they'd be worth the extra.
You can turn them out of the pots and check the root growth so you know you're getting good value.

I just need something to stop people treading on them or the bin men putting the bins on top of them until they grow a bit, I think. I will try to find more established ones but I think the garden centre near me doesn't have the yellow variegated variety that I think would look peachy!
