Setup a SAAS Application -- 2

I am looking for someone who can help me setup a SAAS application. Specifically, I need an experienced developer to help me configure a Billing and Accounting software and host it in the cloud. Furthermore, I would like the application to be customised according to my requirements. The developer should have experience with SAAS applications and be familiar with set up, customisation and hosting in the cloud solutions. If you believe you have the skills required to help me with this project, please get in touch.
