Hey there,
My name is Sam, I have a Master's in Computer Science from DePaul University, Chicago and have been doing web development with my small team ever since I left my job at CDW, Madison. I have worked with clients and companies including Sears, Target, punch stock, tire rack, NASDAQ and Harley Davidson.
1) I have worked with Porto theme before, so it won't be an issue.
2) I have worked on nexcess servers tons of times before.
3) I need details of these changes as it is unclear, what changes you require (can do for 15$ / hour though).
4) To upload images, I need all the images placed in one directory or you just need to provide me FTP and Backend details from old site & new site also, and leave rest to me.
Other then this, the things that you require are pretty easy in Magento.
I can share details of site which have PAYMENT CONFIRMATION mails and BANK accounts connected to it, but as I've signed ND Agreements with my clients I will share details over Skype if needed. My id is 'datasofttechnology'.
Kind regards,
Sam
