Drupal expert needed for expanding existing Drupal site and for a new site

I am a marketing consultant and offer my clients innovative websites focused on growing their business and providing measurable results. We created a Drupal site last year for a customer and are looking for someone to maintain and expand it as well as to work on a new project.

Here are the brief details with more information being provided to shortlisted individuals/companies

1) Terem (www.terem.com)
After 8 months of development, this Drupal site went live in April and we have got some very good feedback. We now need to make some changes including:
- Adding Arabic as a 3rd language
- Adding 2 more clinics which requires coding for the side bar table showing the wait times and the table on this page: http://www.terem.com/%D7%9E%D7%A8%D7%A4%D7%90%D7%95%D7%AA-%D7%98%D7%A8%D7%9D
- Making minor theme changes to the home page and site template including moving the language selectors to make them clearer.
- Setting up automatic backups to an external server and writing up a restore procedure.

2) Second Opinion Radiology
I have a customer who is a radiologist and wants to set up a multi-lingual site offering to read X-rays, ultrasounds and CT scans and give second opinions. The site will be fairly simple (Home, About, Services, FAQs, Order Now, Contact) since he only offers one service however it must allow for a clear 3 step process:
- Select urgency (3 day or 24 hr)
- Make payment online
- Upload files
The site will initially be in English and Ivrit with other languages being added later. The target market is Israel and New York State (where the radiologist is licensed). I have a graphic designer who will create the logo and PSD's for the site and I want to know what budget you envision to take these PSD's and implement them in drupal together with the file upload and payment functionality.

A detailed spec will follow for qualified candidates, but I'd like to know if you are interested/able to take these on in the next 1 - 3 months and if you can suggest budgets so that I can quote to the customers.
