Ebay is a massive business matching buyers to sellers of
products.
Could something similar work matching customers to
service providers?eg. for window cleaning: customers submit a request for a quote online with maybe even some digi photos of their premises. It might be useful to have a template customers would fill in, providing the typical info a window cleaner tendering for the job would want to know. Then window cleaners bid for the job. Like ebay you could have feedback etc. so that the customer could accept not just on basis of price but what you're reputation is like etc.
If it works with window cleaning, it could maybe be expanded to other services and trades.
Probably got lots of flaws, but hey just an idea....
I'm not gonna do anything about it but if one of you budding Richard Bransons out there want to do it go ahead!
