Mike,
Shops are doing what they can to sell you an item.
They may offer discounts, special offers, value added services, even a general interior design service.
They make their profit on the item, and they have to employ the saleperson anyway.
Someone holding a five week certificate as an Interior Designer may be available, and may be working within their competence to offer advice.
You have to ask yourself what level of advice you really want and get your head around your desires by looking at other interiors and catalogues and so forth.
There seems to be little point in talking to a shop sales assistant about colour if they haven't FIRST assessed you needs and likes and dislikes by visiting the house and viewing any interiors you'd like, taking your instruction and coming up with a proper proposal - if they did, well and good.
Many do not and you may end up walking out with a selection of paint tins and papers you may not eventually use in the end.
Interior design services need to be tailored to a client's particular home and their specific needs and may need several consultations.
Sometimes a lot of time is spent wandering around looking for the right fabric at the right price and this research time feeds into the final result.
Ask yourself what you can buy for €100 nowadays and whether the time spent with your takes into account the research and design time done away from you.
