Finding a freelancer or professional to help you with your tasks is not that hard these days. Sites such as Guru.com put you in touch with people who are willing to help you out with your cause. You could always create your own site to connect employers with employees. Project Bidding Theme is just the theme for the job.

The Project theme has virtual credit and escrow features. A mobile version is also available. PayPal, Payza, and many other gateways are supported. The theme offers Facebook and Twitter integration.
The Project theme is great for project-bidding sites. There are many of those sites around but this could work fine for niche job sites.
