Wordpres Simple Custom Task 2

Hello everyone, I have some tasks to make to my wordpress site ( i will send you the link in pm) I have a wordpress site with wp-rentals theme. The idea of the site is: a. Managers can insert properties and owners. b. owners can change their properties, and put limits (of energy, water and gas use) to a custom IoT widget we created c. tenants can see the limit and measurement Everyone from above can call a taxi, a cleaning service or breakfast with the custom widget we created. a.(15 usd) add some checkbox to our widget's cleaning services, so the owners, managers or tenants can choose from beds, toilet, kitchen cleaning etc.. so there is a total cost of the service. Also add a second field for email or sms for each of the partner on "edit property" page so if the first choice cannot serve, there is a second choice (maybe after 15 minutes of unconfirmed order it triggers, that part you will do in task b i just inform you) b. (50 usd) create a confirmation system. When a taxi partner or cleaning service partner, or technician partner takes an sms or mail order, he should send a blank sms or mail as a reply to confirm the order. If not after 15minutes (variable), the mail with the order is sent to the second choice. c. (20 usd)help me connect with our sms server and add sms fields (i only have email fields now but you will create sms fields at the first part) I will provide you with the sms server credentials. We have time but our budget is a little bit restricted. Ratings, professionalism, low budget and polite conversation will be a plus for choosing you :) I would be happy to work with you! Happy bidding!
