Dear Jfeka, I would like to work on this project. I am an expert in MS Access and all it's features, especially in accounting, reporting and interface feature creation. I also have a strong fluency of Spanish, not so much in listening (often times it is too fast) but in reading and writing, I can confidently meet your requirements for a Spanish user interface. I would recommend a proof-read, as I am sure you would want to do that as well. I am familiar with Quickbooks, and can provide a bright, intuitive interface like the Quickbooks interface, with custom graphics and, if you wish, the ability to change the graphic theme. I am able to create interfaces with immediate access to the important areas of the interface, such as customer account transactions, invoice creation and management, etc.. I am also experienced in traffic software, this meaning that I am able to build databases that can invoice and keep track of what has already been invoiced, paid, still needs to be, etc.. I am able to build-in any functions required, and would also provide a detailed account of the database structure and methods, so that you could easily modify it in the future. Please let me know if any questions! Thank you, Kenneth
