Build a website for aagc.in

We already have an active website supported by wix.com. However we wanted to upgrade the same keeping in mind the best practices of the industries and increasing the traffic and conversions. We currently have a traction of about 400-500 monthly users. The idea is to increase the same atleast 10x. We have already used the best features available on Wix and would certainly look forward for assistance on SEO. We also intend to build a task journey allocated to each client on the website and a due date calendar linked to master database to keep a track of things. We are looking for a long term contractual agreement. Kindly share your quotes accordingly alongwith samples of work done in the past and a broad outline of the idea you propose to implement. Further a detailed breakup of all cost associated in the process should be shared with us for the ease of decision making. Speedy Response will be appreciated. The domain of the website is registered on Bigrock is separately owned
