Hi all,
Thanks for all the replies and support.! I thought I'd give everyone some more information about the reasons its so hard to bring this app back on sale, been banging my head off the wall for weeks on this!
There are only 4 or 5 companies in the UK that are allowed to "resell" DVLA data. Most of these companies don't simply sell it on, they cleanse and enhance the data then sell it on. However they don't sell on the actual data, they sell on services to query the data.
And to give you an example, on average EACH query for data is charged at around 20p - 80p. So as you can see, i'm trying to fit a square peg in a round house selling an app for 59p!
Also I am not allowed to simple sell on the raw results of a query, you are really meant to use the data to enrich something.
So far I have paid for 2 commerical car databases (e.g. Makes, Models, Specs, etc) but they are full of missing data and there is no consistancy with regards to model names (e.g. Mazda RX8, RX-8, RX8 231).
My goal just now is 2-fold.
a) Get access to a good car spec database (containing thing like BHP, MPG, etc)
b) Find a provider who will provide me a service where I can pay a small free per search (say 5p) and they will give me back limited data which I can thing link to the car spec database and bring back loads of useful data.
If the about 2 were in place then I could provide the app for free and sell the searches in bundles, for example 10p-15p a search or something sold as a bundle of say 10 searches for 99p. Although I imagine the cost would be slightly more than that since the cost of the server-side infrastructure, database costs, dev costs etc would push it up a little.
Anyway, there is another little mind dump for you all to read

If anybody has any suggestions then I would love to hear them!
Paul
