Hi there, I'm Matt Sergei (do call me Matt, please) and can create your application -
please provide more details (Windows or Mac app, screenshot full size - main screen? E.g. if a user has several displays, how/what task to create etc).
Currently busy with other projects unless this is really all you need. Otherwise a webmaster and developer for 26 years. I'm incorporated and this is my lowest offer possible.
Regards and hope you're safe,
Matt
