Charity Site using VirtueMart repaired

I have a charity website ([login to view URL]) running Joomla! that has a shop set up using Virtuemart on it. (Please note this is switched off at present). I need someone to help sort out the PayPal and shopping cart on it. Sad to say that because the site has been virtually hacked to death, and I have had to put extra security onto it to try and keep it secure, I will only give the access codes to the back end to the person(s) whom I think are really going to help. Sorry and please do not take offense. Please, Please DO NOT attempt to login to the admin area as you are likely to get banned by the software that I am using. If you want to see the admin section you will need to contact me first for the login details, as I said these will be given the those I feel are going to help. The website is as I said a charity website, and I have been really grateful to people on here that have helped, paid for of course, with repairing it and setting up some security for me. I need more security I think. But as it is a charity and we DO NOT have any funds sadly I can only look at the bids that are for doing the repairs that are within the band that I have set, anything out of which will be disregarded. Yes I know you only get what you pay for, but until such times as we can generate funds, that is why I have set the shop up using Virtuemart, we cannot afford much. So please can someone help sort things out for us without costing an arm and a leg. James
