If you are a web designer or developer then there may come a time when you really need to push your services in order to bring in more work and expand. Before you expand you need to ensure that you are ready to take on the extra work. This means not just having the time to do the designing or programming but also the time for the admin that may be involved. It could be that you decide to employ someone else to work for you which would mean changing the business structure if you are currently self employed.
Finding good programmers and designers is very hard. You need to ensure that they are reliable and trustworthy and that they are able to work to deadlines. Deadlines are vital when working on web projects as you may need to get a website live for a certain date. Ideally, you need to work back from the live date to plan when you want the designs to be finished and then when the programming will be completed giving you plenty of time to test the site before setting it live. You can also then give your clients timelines for when you need the content and images etc.
