No you must not actively promote your business with the aim of obtaining paid work when responding to a ProBit request. If we see anyone doing this we may need to restrict their site access as no-one come to ProBo to be sold to. However, similarly to when you pitch for new paid work, by answering a ProBit request you are demonstrating your skills and abilities to potential future clients and is a highly effective way of marketing your business in a more innovative and practical way.
