Just check what I can do for you. I'm a programmer. I studied in an American college, I speak, write and generally communicate in English perfectly. I have worked for many computer companies and I have my own company since 2003. I write programs, that can read the data from websites or files -eg excel, access, text etc- and produce the exact output you want. Once I write the code the only thing I have to do is press a button and wait for the data to be collected or modified. This is much faster that manually entering data and it prevents errors done from copy-paste. Since I write the code only once, I can parse any number of records without extra cost. The only thing you pay for is the code. Once the program is ready I can parse unlimited number of records. Also if you want to do the same job at the future, eg scan again a website for changes, or want additional data, I can run the code again without having to create it. 收起
