Customise saleforce and gmail configuration

We require a Salesforce and Gmail expert to make a series of customisation changes to the system so that it works as we require. Some of the changes are very minor (e.g. add our company logo), ammend task field to contain a drop down list of choices etc. We also need events involving meetings with customers to be created in salesforce, which creates a calander entry in a specific gmail calander. Also the customer needs to receive notification of the appointment, if they have supplied their email address. We have 7 users on "group" edition of Salesforce for our sales team. We use Google Apps, and gmail as the email server. It is likely that there is additional customisation work going forward so this should be seen as part of a longer term relationship for the right individual. The successful person should be able to speak good English, have access to Skype, be prepared to "Share Screen" to help show what is required. I would expect to pay on a hourly rate due to the variable nature of the requirements.
