If you are self-employed and have to find your own work, you always need to have a plan as to where you would like to take the business over the next few years. It may be that you want to see a steady growth in sales from the products or services you already offer or that you would like to expand into other areas. If you are looking at offering other products and services at a later date then it is important to start doing your research early. Find out what additional costs may be involved, if you will need any additional training and any extra insurances / legal requirements you may need to get in place. Once you have this you can make a plan deciding on a date you want to have it all up and running. You can then work backwards and give yourself deadlines as to when you need to have certain things in place or completed.
If you are looking to expand geographically, then again you will need to carefully consider how you are going to do this. It may be that you use social media or paid for ads to boost your geographical reach or possibly that you do leaflet dropping and door to door sales.
