Another Switch Clock

Unfortunately, I have no time left to develop a new idea:
I want a new type of switch clock; main purposes: switching on an electric heater in the morning or an electric blanket in the evening:
requirements:
- directly powered by 220Volt
- contains clock (with limited display capabilities, maybe 1 piece of 7-digit LED display is enough)
- No hardware relay, but solid state relay up to 10A.
- small backup battery
- must fit in small case (a case which has a 220volt plug and socket in the housing, so it can be easily plugged into a wall -outlet)
- 50 Hz from the power grid can be used as time-reference
Functions:
- the relay is closed at a settable time (E.G 06:00 in the morning)
- switch off is performed by button press manually
- the 'alarm' is rearmed for the next event (the next 06:00 the next morning)
- an overrule button to manually switch on.
- a third button for a timer-event: e.g switch on manually (start timer) for 30 minutes.
Of course, these 3 buttons can also be used to adjust the clock, the alarm and the timer.
Anybody fancy in developing this?
Many thanks, Geert

Hello,
of course such a design is possible, what as you know time is money, and what would be the commercial issue ? Are you ready to pay for that work ?
