"Check if we are available in your area"-form

Hi!

I have a website for my application, but the area where we operate with our services are limited to some city parts.

Have anyone been able to create a form, where you put in your adress (with Google API/autofill), to check if we’re available in that area? If yes, you get redirected to a download link, if no, you get redirected to a mail signup.

Thanks in advance
