To go with Right choice is very difficult for a client . So, would like to share some qualities without which there is little a designing company or even an freelance designer could accomplish or where a design company cannot survive without performing well .
Delivery and Efficiency : Clients want their work in the time frame they have agreed upon for, timely completion of the project it is part of . Hence, client discusses everything with the designer ranging from complexity to nature of the project so that there is no miscommunication from his end .In case, designer is not able to give exact time in which the project might be expected, client is bound to look for another service provider.
Creativity : While there is an army of freelance web designers offering their services on web, there are few apt enough to bring in the element of creativity . Find their work flow or creativity from their past work "Portfolio page" .
Regard for Latest Design Advancements : Newer updates offer more scope of experimentation with content and design. So, there is no point in hiring a designer that is only comfortable with Stone Age design tools .
Industry Familiarity : Better to hire expert that has the experience of handling projects from different fields or at least in the field you are active in .
Client Consultation : Client knows what he requires and nothing comes out of keeping him out of the loop while making a design. Hence, a designer who consults clients at different stages of designing is less prone to make major errors as clients are likely to point out the mistaken areas.
