Paypal Payments Pro HOSTED VERSION Integration onto existing website

OKay basically, I have a website: www.printing360.co.uk. Currently I have got the paypal payments pro account and my website is set up to allow customers to make payments on my website without actually leaving my site. However because of PCI compliance hassle, I want to switch my shopping cart to the paypal payments pro HOSTED option, so that I don't need to worry about the PCI compliance aspects. Just to clarify my website is already built and coded with the paypal payment gateway, but I now need my shopping cart changed to accommodate the HOSTED version of the payments pro solutions. I would also like the checkout express to be integrated on my website. Please let me know before bidding if you have any experience in this, and your expertise in this area. I also have an SSL security certificate installed so this must be changed to accommodate the new changes. My maximum budget for this project is $50-70. I will need web developers and coders to maintain my website so if you are good I will employ you on a regular basis for all the changes I need done on the website.
