Directory/Website Like TeachStreet!

Hi We are looking for something similar to [login to view URL] - the website will be very similar in functionality, where we are targeting a certain market in the UK. The companies will be able to post a listing, and users can also rate them and directly contact them. The layout has to be just as user friendly as TeachStreet and latest web 2.0 technologies - SEO optmisable, optional payment system, registration for the companies, communication on homepage, blog etc... Have a look at TeachStreet and tell me if you can delivery something similar in design and features. Firstly, I need to know you are capable of delivering a task like this, so past work must be shown of websites you have made. We belive that [login to view URL] can be used as a solid base for this, in fact it includes almost all the features we want, so we are really just looking for someone that can build the ideal template on this powerful tool....If you have any suggestions yourself then please suggest in the PM. The idea is to keep work to a minimum for you, and keep costs low for ourselves. Please note that I have had some good quotes already so only serious offers will be considered. Any further questions, just ask. The winner of the bid, if they do a good job, will also be used for future jobs, as well as other projects we have planned. Looking to establish a good relationship with a good PHP/Web Designer... Thank you David
