Lead generation b 2 b retail stores uk

we are importers and manufacturers for more than 20 years of our own branded range of "Hoppa" shopping trolleys in the UK and Europe.
we sell B to C and some limited B to B.
we would now like to expand our B to B customer base.
Our objective is to have 1 retail outlet per shopping street throughout the UK and Ireland.
Shopping trolleys are very popular in the UK and our Hoppa brand is extremely well known nationally.
we would like you to create a clean list of independent retailers initially and outlets who already sell shopping trolleys and similar stores who currently dont stock them we can target.
we have our own logistical warehouse in Essex that can send cartons anywhere in the UK established for many years ND.
we have an award winning range of trolleys.
we would like to take proforma orders on our trade website -USB International Ltd - and first only target the Hoppa brand and only shopping trolleys.
once we have a good clean list, we can start an email campaign to target these potential customers. we will also hire someone on Upwork to cold call the list of customers.
we do own several other well established brands that can be seen on this website .
the website will be similar to our B to c websites in that retail/trade customers will be able to login, see the prices, place orders , check out and we will despatch to their retail outlet. All prices are delivered to the UK ( with a surcharge on any outlying postcodes which will be transparent before any order is placed)
we are established for over 30 years and just want to sell B to B as well as B to C on our own website and offer trade customers great shopping trolleys that sell very well and are well recognised by the public already.
if we can get 500 good independent buying customers we will be extremely happy.
after this we will target our other brands to the same customers who can buy these as well as other types of retail outlets.
Next we will target retail outlets in De/Fr/Es/It and rest of EU as we have 3 warehouses covering our B to C websites in Europe and we will follow exactly the same principle in the EU and distribute from our EU warehouses where again we have ND delivery at very favourable rates.
