Please share details of all that exists / inputs that need to be inserted in database etc. This will help me determine the best solution and also enable me to assess scope of work precisely. I will revise / confirm my bid accordingly. Detailed specifications and inputs will also help me to make an informed commitment and deliver as required.
I commit only if I am confident of delivering and once committed, I ensure a very thorough job and also support if you need changes / enhancements in future. I look forward to hearing from you and working on the project.
