Hey Paddy,
I'm sending you this email because I need to let you know that the demands of my own buisness are increasing to such an extent that I don't feel able to provide you with the service you need. Due to these demands I feel that I can't devote enough time to Lucion and I can't prioritise Lucion work. I don't feel good about this because I feel like I'm not offering the level of service I'd like to give you guys.
Obviously it's not my intention to leave anything unfinished and I don't want you to feel like you've been left in the the lurch by me. I will more than happily finish up all outstanding work that we discussed in our last meeting (the Asbestosthetruth.com website and the email capture on GreenPassport.net). After this I just can't take anything further on but of course I will do a complete and thorough handover to whoever you choose to take the work forward.
If there is ever a technical problem with the websites or something just blows up I want you to feel you can get in touch with me straight away if you need to. I'll always be around and available to you because I've enjoyed working with you and Lucion over the past year.
I understand if you're a bit pissed off with me about this as I know it will create a problem for you but I think in the long run you would be more pissed off with me if I didn't provide a good service. I value our friendship a lot which is why I really don't want to piss you off but also why I need to tell you the truth.
Hope you understand. Let me know what you think and how you want to proceed.
Dave
