I am an intermediate filemaker developer from the Philippines, although I don't have any filemaker certificate to show but I've been creating flemaker solutions for almost 3 years. I've done solutions such as product sales & inventory, expenses, high school registration & collection of payment, lendng, check writing, pawnshop system & etc.
For the project, we will import all of your address data to the address table and in the subscribers table I will use dropdown field and select the address from the address table, this way you will never get wrong in taking down address even over the phone.
You can reach me in my cellphone number +63 917-6300150.
Thank you,
Dennis
