    I know you get this request all the time and I am in now way trying to low ball this project. I studied math and many of my peer in university studied computer science and I first hand know this is a huge project. But I also know the average going rates for software development so lets play fair ball pure business/service. I need to develop a website with a monthly registration fee as well as a very small transaction fee. As you may know Vaporizers and associated items are becoming a large consumer interest. I am the founder of Vaporize-IT Distribution Corp. I have created a web or net between local (socal) wholesalers and local (socal) retailers. BUt this is growing to large for me to manage on my own. My niche is that &quot;on hand inventory&quot; is deliverable within 6 hrs and my &quot;on call inventory&quot; is available in 24 hours. We mark up the item on average (emphasis) average 35%. My on hand inventory is once the order is received is delivered by a driver within 6 hrs and my on call is delivered by a drivr within 24hrs. BUT! I want to give a retailer the option of being a wholesaler as well for certain items. If they must order some they might as well order a lot and wholesale a portion to another retailer. THey can choose to send it themselves, or have a driver of mine pick it up and deliver the item for an added cost than can be divided by both parties evenly. THe seller should be able to choose his payment option be it Cash on Delivery or Cash on Order. It is imperative that this site is exclsively for retailers (who identity should be masked with only location of store available to view to prevent retailers fueling neighboring competing stores. This exclusivity can be maintained by invite only memebership. Im willing to put up funds to have this done well for I feel it has a huge growth potential.

    Our two iPad applications were developed by a freelancer who I can no longer get in contact with. The freelancer provisioned the applications to our iPads using TestFlight. We now have an Apple Enterprise account and need the apps provisioned so that they can be installed on any device using the features of the enterprise account.In addition, the applications have a few bugs that need to be worked out. Both apps use a web view to host a UI off of our server. The apps detect when certain pages are loaded and then allow an interface with the iPad camera. One app allows photos to be taken and posts a photo to the server via the web. The other app reads a bar code and goes to the website encoded in the barcode. Both apps work, but have minor bugs that need to be addressed which I can give details on later.Please do not apply unless you are a highly experienced IOS developer. I need someone who knows what they are doing and have no patience for developers who cannot clearly communicate and quickly understand what needs to be done.
