Re: Depends on what you want
Before retiring I worked in the Civil and Public Services, ran companies for a banker, and then my own technical consultancy. Here is an outline proposal for somebody to create a "top line" system:-
Scoping the problem: 2 leads, 3 person-months total £100,000; 4 juniors, 6 person-months £150,000. Overheads: leases, accomodation, travel & expenses £250,000.
System: 4 basic servers running BSD with hot swappable drives (R350s? should be overkill at ~£2,000 each) i.e. a web server; one Running Python and SQLite; the other 2 as cold backup servers; cabling, etc. £2,000 - £10,000. Software cost ~£0.
"Consultancy" fees, etc.: £9,500,000 (Bolly isn't cheap). Total spend £10,010,000.
Looking at it again, I might have over-specced the hardware...
