How to determine the complexity of the work
Carefully review the details of the work. If you have not carried out similar tasks previously, a preliminary assessment should be carried out with special attention. Make sure that the job remained unclear moments for you. Discuss with management any questions and again please specify what results you expect.
Compare this work with similar. If you need to determine the level of the fee, do some price research. Call companies providing similar services, and then determine the average cost of performing a similar scope of work.
Consider the resources required to complete the work. Very often all sorts of hidden costs (both time and financial) can seriously affect profits and the end result. For example, if you are asked to make repairs on the customer's materials, don't forget about the cost of tools and involved workforce.
Try to find a specialist to perform this work on behalf of the customer. In this case, you will be able to easily get a detailed assessment of the work of those people who have already done it and are well versed in all the intricacies.
Make sure you have enough time, forces and knowledge to complete this work. For example, even if you are fluent in foreign language, technical translation may cause you serious difficulties due to the large number of complex terminology. In addition, for the specialist in this area can be very simple.
