Hi,
Please can you tell me more about your desktop version (maybe website address also) so I can get a feel for it and if you have any other information this will be great for me to look at and get back to you with a realistic bid on this project.
I have done these types of projects before, so look forward to reviewing more information and getting back to you soon.
Can you show some pictures from your desktop version etc or have fuller specifications so I can work on some things?
Thanks,
Pete
