Magento expert wanted for launch of new Magento store

This is not a big job, we are launching our new website this week, and we will encounter some errors when transfering to a live domain. We currently have a problem with the payments as it is not directing to the Paypal/Sagepay website. We need someone who will fix any problems we have in order to take orders. We think there will be a maximum of 10 problems, ranging from the above, to moving blocks of information, to aligning a bit of test, inserting a new page or telling us why we can't submit to a website. Again, this is not going to be a big job, and there may only be a couple of problems. We just need someone who can be there on the day, on Freelancer messenger to allow us to tell you the problems and get them sorted so we can start taking orders. We expect the bid to be $30 maximum for this, if you bid this and you can show us that you have a good understanding of Magento, then the job is yours. Remember, if there are only a couple of issues, you will still get the $30. Any more than 10 issues and we will create another project for $30 and pay you another $30. Thanks
