branding for a new product

I'm Steven Bray and we run a company that sells Solar PV – which are solar systems that generate electricity. We want to offer a suite of offerings, into one “product”. The total offering we are looking to sell, is as follows: Joe Bloggs runs a business spending €10,000 per year on electricity. • We sell him a solar system to generate his daytime electricity free of charge • We supply him with his mains grid electricity at lower rates to his current purchase price from the grid • We also purchase his spare electricity back from him (if business is closed at weekend for example, there will be lots of spare electricity at the weekend) • We get him 30% grant funding towards the cost of the solar system installation o We can also offer him an LED lighting upgrade for the building if this is relevant to the business Joe Bloggs will have an outlay of €30,000 after the grants are deducted His electric bills will drop to €5,000 He has a payback of 6 years on his investment I'm reaching out to companies to see if they can package all the above into a neat package with a brand name, story, perhaps a logo but I'm happy to take advice here. It will be marketed through our website. We have already engaged with a marketing company to promote the product online, but they don’t deal with branding or the above items. Could you review the above and come back with a proposal please? All entrants must have perfect English and strong examples of previous branding projects (not marketing projects) Feel free to ask questions should you have any. Many thanks, Steven
