We are a team of web designers and developers with 800+ sites to our credit. We have developed and integrated custom CMS for many of these sites.
I request for more details about the requirement - how many pages your site will have, what will they be? which of them do you need to manage through CMS, inputs that you will provide - logo, contents, graphics; any creative direction (reference sites that you like or design preferences).
The above will help me assess scope of work and I will revise my bid accordingly.
I look forward to hearing from you.
