I have thought about it alot and really there are two different things here and it starts to get rather complex.
1) Blockchain/Coins - "PKB" - Decentralised not controlled by anyone
2) The company - "ParkByte Limited" - Currently 100% controlled and owned by myself - This is where the equity would come from for the crowdfunding
I think the best way forward is to keep these separate. The main reason is to not restrict other established parking companies from adopting and integrating PKB into their own apps.
The thing is ParkByte Limited will start to compete for business against established companies like RingGo and PayByPhone while at the same time wanting to join forces to use PKB by providing much of the infrastructure.
The established companies are key to quick adoption and the success of PKB because they have established contracts already in place and they usually last 5 years+.
For these companies it should be as simple as offering a new payment method that drastically reduce the fees paid to the payment service providers (Credit Card processors).
I would like there to be 2-3 established companies partnered up with ParkByte Limited using the same APP/wallet for payments by PKB, each paying ParkByte Limited a "lifetime discounted early adopter fee" for an annual subscription to support the infrastructure provided by ParkByte Limited such as the APP, Support and other development. They would also get a slice of the premine as previously mentioned.
Any company wishing to join after the partnerships have been made will have to pay a normal annual subscription fee to use the ParkByte Limited infrastructure.
I would then look at getting ParkByte Limited competing directly with the early adopters by bidding for tenders, running services exactly like theirs maybe having to go down the Credit Card routes aswell.
My main focus at the moment is getting PKB adopted by providing real life benefits and solutions, if PKB gets some interest from established parking companies and there are signs of it being adopted that volume on exchanges would shoot up fast, Currently not many in the crypto community know about the project/coin and after all there are only 4.7m PKB around, 922k of which is held in cold storage from the premine.
The figures I mentioned in my previous post were all rough guesses and I have only received one response so far to my Freedom of Information Act requests. To give you an idea of the size of the market (This is a relatively small council, Edinburgh for instance have on their website they took £5,531,715.18 from cashless parking) ...
1st April 2015 - 31st March 2016 - £1,216,152.63 income from 209,751 transactions, using the parking industry basic handling fee of 8.8% (found on a few public documents, others listed per transaction etc work out around the same 8.8% seems to be the marker).
£107,021.43 was spent on processing cashless parking transactions in the last year by 1 council (there are over 200 with parking services in UK), needless to say ParkByte infrastructure costing £0.05/transaction and with a 1% PKB-to-GBP service like BitPay offer for BTC that would of been £22,649.08, not much of a saving
I won't be doing any sort of coin sale like I think you are suggesting and I don't have any numbers really in mind for the crowdfunding investment into ParkByte Limited, probably maximum of 20% of equity in exchange for an unknown figure.
