If I were you I would take a neutral point of view and get info. from:
OPI,
LCN,
EZ FLOW,
Creative,
AZKENT,
GRAFTON (ibd,etc)
Millenium,
Oydessey,
NSI,
Backscratchers,
Alessandro,
The Edge,
Ceteum,
as your on the internet do a search there are about 40 companies in the UK.
Basically you want a product that will serve your commercial needs and give you pleasure to work with.
Ring them all and get an info. pack. Weigh up the pros and cons on cost of product and training and future products etc, you would be surprised how the costs vary when you add it all up from start of training to end. Don't be caught out by the attractiveness of "starter" training add in all the training they offer and the full cost of products used as invariably they make you buy "extra" products on the first day to make their "starter packs" look cheap.
From what I understand EZ Flow has got the best commercial L & P at the moment. But that's only an opinion garnered from the trade.
Even more importantly ask about the profitability, one product may seem cheap until you realise how much you have to use to make a full set!
Also look for something which has a full range of products and a genuine concept behind their products with new products coming out as well. This way as your business grows you don't have to find other suppliers. Beware of companies that have "bolt-on manicure and pedicure" that are afterthoughts. Invariably you'll need another supplier!
