Rebecca hostile to start with I'd go for one of each colour, depending what system you are using some colours you may be able to layer to create other colours and if you havea. Selection of glitters etc also then can create other colours too. So I'd say French pink and white and the French pink can also be used on its own as a nude/ pale colour, a red, bright pink, blue, green, purple, black, grey...your black and white are also good for nail art or underneath other colours to make them brighter( white under) or darker ( black under). You can never go wrong with pinks and reds, always popular...then as you get to know clients you will see the colours they tend to go for more ands to I up on those and the colours you aren't using either use them up in rock stars or wear them yourself...whatever we have on clients always want...don't forget to take pics of your work, always better to get an idea on he what colours look like by seeing them on hands rather than on colour pops/ wheels
Which system are you buying into? May make it easier to advise?
As for printing when you are starting out I would say vistaprint is great as you only need order as many as you like so can budget yourself, also if you leave order in your basket for few days they will email you with other offers, try and make most of their free things as well , I think you can have four free items at a time!! Once you are established and going through more price lists/ business cars I would recommend searching around for your best price for bulk ordering but also remember if you are going to be adding new things to your price lists soon don't Order too many until you have added everything ( hope that makes sense) also Xmas/ valentines/ summer offers leaflets don't order too many as you will be left with them!!
When I opened my salon I used Carl at verve print for my designs and banner penguin for my printing and have to say the quality is fantastic...even clients have commented on my price lists and gift vouchers x
