You should create a checklist of everything you need in your application form so a template can be found to match your needs. This will help you to find a form that will suit your needs. If you do not mind paying for a template for your application form, you can actually pay to have one created expressly for you that will match everything on your list and create the perfect form you need.
On the other hand, a detriment of using a pre-written template is that it may not handle more complex jobs or specific types of contract projects where there are a lot of detailed deliverables. Obviously, a basic form contract is unlikely to cover all the bases for things like international joint ventures, multi-level sales agency relationships, or insurance services. These are agreements where the costs of an attorney are justified.
