I require an initial down payment of 50% of the overall cost (if the cost of $1000 and below) and then require the rest when the web site is fully completed. The first 2 days I will write up what is called a Software Requirements Document (SRS) which will provide you with an understandable approach on what is required to get certain aspects of your site done. Then, I will proceed to write a specifications document that will allow you to know how I will do it. You will keep this document. It is beneficial because, in the near future, you can use these documents and give it to anyone who will work on the site and they will be able to quickly understand how it works and to zero in on any problems. I have been working in this business for several years in the coporate enviroment. I use a lot of the approach that I have done in the corporate level with my clients. I don't just create product to sell and move on. I ensure that it is maintainable, well structured and professionally managed.
