Need a functional app like incomee.co built using bubble.io

Hi, we are looking for someone who could build a functional app like incomee.co. Not the landing page, but the flow from signup and internal functionalities. The idea is not exactly same, but something that is of similar. Not all features are required. What we want just has 3-4 pages. Collect some data from user, integrate emails and Whatsapp API, generate invoice, etc.

We want in 1 week from the time you pickup. All design and flow details will be provided on accepting project.
