Hello sir,
I'm able to do this job for you. The amount of time needed depends on how the data can be retrieved from the source - distributors / manufactures websites (how many websites, how well are the data organized etc.). But I think, I can get it done in 12 days, with a little reserve...
I have more then 15 years experience with Excel, I must say, that I'm not an expert (writing macros for example), but I know the most of the functions (formulas, cell formats, ...) well.
Microsoft Snipping Tool - pretty straight forward software...
FTP - I know how and where to upload files... The question is if I should upload photos through ftp or add them through Opencart Admin... I have high speed internet connection, so uploading photos will be fast...
Currently I'm free, ready for work, so I can start immediately...
If you have any questions, you can contact me through private message.
Regards Daniel
