Hi there! My name is Adam. I’ve just read your project description and I think I've seen this project before. So, maybe this time you will choose me.
I'll clean your Joomla's from malware and move them one by one to separate cPanel accounts. I suppose you have some reseller account with WHM. Great.
I can do it for $25 for a site, not a problem. But I will not upgrade Joomla 2.5 do 3.x at this price. However, I guarantee that your Joomlas 2.5 stay secure. If you do not believe me, you may release a milestone after a month. Not a problem at all. I'm sure because I've cleaned and secured many J!2.5, even J!1.5.
I am highly qualified for this project - I have a 3+ years experience cleaning and securing hacked websites/hosting accounts. Actually, I do it on daily basis as a freelancer (not only at freelancer.com). I'm a server admin in my full-time job (where between amongst I manage few Joomlas in different versions, but it's just small part of my job). So I know what is DNS :-D
I can tell you now why you've been hacked: all J! older than 3.4 are vulnerable. And without experience, it's impossible to clean Joomla from malware. Also, there may be malware above your 'public_html' folder, in cron etc.
Summarizing:
- I'll clean, secure and move any Joomla for $25
- I'll not upgrade to other, 'main' version (1.x->3.x, 2.x->3.x etc)
- I'll not do it 'in 8 hours from now' (time difference, other tasks etc.) but I'll do it ASAP
Ok, let me know what do you think :)
Regards,
Adam
