Fix a few Magento bugs

We have a Magento store set up with Simple Products. But we need to add options (via attributes) so that each option can be given a stock quantity.
Need someone to get this up and running and modify as many of the products as possible in 1 hour.

If I like and trust the person who does this, there are more jobs to do for an additional budget.

Please indicate your availability to start.

Thanks,
Simon
