Internet Savvy Ideas Support & Sponsorship Advice?

Dealing with a to-do list can be both frightening and exhilerating.....!!!!! Learning to delegate is one of life's most gracious lessons. So here goes:

I am a request for support in the following areas:

1 - I will be putting out my own Newsletter to my friends, family and interested followers of our journey. To enable online friends to request the Newsletter, I need to copy and paste the code at the end of each blog entry, there needs to be an opt-in for their name and email address. How would I do it in this particular scenario of posting a new blog entry and having it appear at the bottom of the entry each time? Anyone able to assist me with this?

2 - When I see advertisements on the internet for building a free website within minutes..... what's the catch??? I do need a website, and am loathe to have a webmaster control it. I want to do it myself - ha-ha, does that sound familiar?

3 - I am looking for sponsorship. Not in terms of money, but in terms of "things" which will not cost a company much, but will assist me practically and would give them exposure through my website and weekly Newsletters. Does anyone have resources such as templates of letters which I can utilise to approach my local companies for sponsorship? A friend of mine happened across the path of a French couple with three children travelling through South Africa at the moment in a huge bus, with sponsorship advertising all over the outside of their bus. I realise it should be a win-win for both parties, myself and the sponsors.... I just don't know how to go about it. I'm not looking for a bus, I have a motorhome which is better suited to go into smaller roads, campsites and under trees. (A small RV in American terms.) My fundraiser has let me down, and keeps making promises over a period of months now, and I am choosing to ask for support advice here in the braveheartwomen's network.

Any feedback will be most valuable and appreciated.
Love and honour
