ASP.NET POS Development for Salon Industry

I would like to develop a native yet very lightweight desktop version of a web based POS that I've already created for the salon industry. You must posses great UI and development skills. I would prefer using PostgreSQL but you can advise otherwise. Right off the start, the POS will be designed for multi-location & multi-station operation. I am open to collaborating to make the management & reporting side of this POS online while the POS related tasks reside within the native desktop application. The purpose of multi-location and multi-station is the following: - some of my clients have more than 1 location and would prefer configuring all of their company related settings at once and then seeing real time data being aggregated into reports from all of these locations - each location has more than 1 station to accommodate high volumes of clients. multi-station capability is needed to sync all stations to 1 dynamic master which then syncs back to god db in the cloud. Below is a pretty comprehensive list of all of the features I'd like to incorporate: - Appointments - Point of Sale (ticket handling, discounts, etc.) - Inventory Management - SMS Marketing & Text Message appointment confirmation (via 3rd party API) - Reporting - Employee management & scheduling - Service Management for tiered pricing - Touch screen interface - Credit card processing - some more... A few of our competitors include: - shortcuts dot net - supersalon dot com - salontranscripts dot com - korvue dot com Let me know if you're up for this challenge. I ONLY want to work with freelancers or teams of freelancers that have in-depth knowledge of developing desktop apps with data synchronization & backup/restore capabilities.
