Squarespace Website for Non Profit- Urgent

Hello! I have a potential non profit client (Is not confirm yet) who wants to create a website with the following features: - Individual Walker registration including selection of T-Shirt size - Team Walker registration including selection of T-Shirt size - Ability to apply for sponsorship of different levels online - Individual and team customizable pledge pages - Issuing of tax receipts for pledges only - Reports and exports of registrations, pledges and sponsors I looked at a squarespace site with similar features so it would be something like this: [login to view URL] If you find that it's easier to bring an external platform I am more than happy to hear suggestions. I am the graphic designer and I have a lot of experience working with squarespace so I would only need to have the technical parts develop and the template set up. I have worked in many squarespace sites but I am not a developer my self, and I want to make sure this looks great. I am looking for a good price, but as a designer I know that cheap things come at a bigger cost. I want to hire someone that is great at what they do and Please provide me with a quote and timeline of this project, I am not looking to hire someone because they are cheap but rather because they have the knowledge and experience for this project. I do have a budget and that will come into place but I am a designer my self and I don't believe in free or cheap work. Although this is not a confirm project yet, we do get lots of clients and I always need someone on an ongoing basis! Thank you,
