The reason poles in this country are more expensive than the ones you are buying is down to lots of factors.
For the same reason you as a wfp user could not afford to clean a property for £2.50 yet Joe Bloggs with his ladder on his bike could.
The UK suppliers have many more overheads so have to cover those before any thoughts of profit can be added.
If this idea of yours works then soon you will have to buy more stock, more of your time will be taken up, maybe you will need premises, perhaps staff. Oh look your now competing on the same playing field as the other boys and you are forced to charge what they do.
I like your thinking but I think your being a bit naive.
Plus I am not sure I want to buy from someone who cant spell the country he is buying from
