Dolphin: minor changes plus custom module

We managed to complee most of our site already but need help on 4 items on a dolphin social network. We will do the graphic design ourselves but require the following: 1) We have very minor corrections to be made on a registration form and profile display. We need the exact same information that is being entered on the ‘Vendor registration form’ to appear in the ‘vendor profile’ – it is already 90% completed so we just need a couple more fields to match (Budget: $ 80) 2) We need the ‘Edit vendor profile form’ to match the ‘vendor registration form’ (Budget: $100) 3) We need the ‘upgrade membership’ option to appear on the registration form when people select ANY of the ‘Sexy’ options on the form (Note: we already have the upgrade membership option completed so we just need it to activate during the registration process. (Budget: $160) 4) We need a custom module created where premium members who have ‘Vendor’ accounts can post products or services for sale for a selected data range and that includes a special ‘discounted’ price if a specific number of members join the deal and promise to buy the product or service as a group. (Budget: $500)
