Hello Sally,
Thank you for the project invite!
Do you want this Powerapp for SharePoint site or subsite?
Can you please provide me the details about your business processes so that I can understand this application?
I have been focusing on Microsoft PowerApps and Flow since they introduced and have been following these products from the very beginning. I can create most creative and innovative apps for your organization with all types of environment, with name of the app, creator of the app and with other additional information for you. I will provide you with set of templates for your easy use. A wide selection of data is supported as inputs and a spreadsheet is hosted. Also, I can offer you training, consultancy & support.
I would be happy to set up a convenient time to discuss more about your requirements. Thank you for your time and consideration.
Kindest Regards,
Amit Master.
