I really hope it works for you, but to give you the best chance can I point out some basics, which I hope to have correct! I am not trying to 'knock' your plan, merely give you things to consider.
you say 8 hours to do a 1000 leaflets, i presume to 1000 addresses?
In which case 8 hours = 480 mins. 1000 leaflets in 480 minutes means 1 letter box EVERY 28 seconds, without stopping at all during the day.
Yes, this is correct. It depends on the type of house. I've heard some people say they can do 1000 in 4/5 hours. I guess it depends how fast you walk! When you think about it, walking from one letter box to the next would probably take 15 seconds or so if the driveways aren't too long.
£75 for solo delivery, £35 for shared. So if you have 2 clients, the delivery agent has to do MORE work, and ensure 2 leaflets per door for less revenue to you? I do not see the logic, and I would be shocked if I went to a shop and it was £75 for one or £70 for 2? Surely your discount incentive if they want to share and reduce cost should be over 50% of solo value?
I'm not sure I understand what you're getting at here. £75 for solus means the distributor has to take one leaflet from the bag and post it. They get £50/1000 leaflets. For shared, I charge the client £35 and I get three clients who want to cover the same area at the same time. This brings me in £105. The distributor simply has to take out three leaflets from the bag to post through the letter box. It's not increasing the difficulty or time because they can take out the leaflets as they walk to the next letter box. They walk the same distance to the same houses for £50/1000 leaflets.
Have you researched the cost of other similar services in your area? Are you competitive where you are as here I would think the pricing too high.
Yes. Most charge around £30-£38 for shared, and £70+ for solus.
Would it not benefit to find a company doing a daily / weekly delivery and get them to put it with there product, EG the free weekly paper.
No, because people are much less likely to read the leaflet when it is stuffed inside a free paper. Plus if I did this it would defeat the point of my business!
I hope that gives food for thought, and wish you every success with whichever direction you choose to go in.
