Custom Wordpress theme required

I am looking for someone to create a custom / bespoke Wordpress theme based around vehicle leasing. I have had a plugin created already which you can view by clicking the link, below: [login to view URL] I would like to have this plugin changed in to a theme but with more functionality. The plugin works well but I know it can be better.  I would like the theme to have the same functionality as the weaver 2010 theme where everything is customisable but would like the back end to look professional and very similar to the control panels on premium Wordpress themes such as premium press directory and others alike. The theme should allow the display of vehicle offs by make, body type and price. Each offer should have its own contact form and the ability to add images. I would also like to look at the possibility of uploading vehicle offers from an excel spreadsheet or CSV with the ability of pulling images from a media library to fit with each vehicle offer. There is also a random offers plugin which has also been created which shows random offers in the site bars, this is currently a widget and can be used or not used depending on the page. The plugin at present allows me to set an expiry date and the vehicle should disappear from view but I am not sure if this is working correctly but this would need to be included. I have purchased a car sales theme which works well but is geared towards car sales and not leasing. This can be seen at: [login to view URL] This also has the ability to upload offers from a spreadsheet but I have not tried it yet. I would ideally like someone who understands the requirements above, is very creative and would be around in the future to help develop the theme but also input their own ideas to make it better. Any questions welcome.....
