Update and Improve a Wordpress & Vantage Theme Site. Potential for future part ownership.

Hello everybody. My name is Peter and I am the owner of www.gusty.ie. I set up [login to view URL], using wordpress and a vantage theme. The site is currently live. There are a few changes I would like to make. These include 1) changing the web domain name to another I own, [login to view URL] and 2) Creating an alternative home page to the blog one that exists. The ultimate aim of the website is to provide a buy and sell platform for outdoor sports equipment, specifically, boards (surf and sail) bikes and kites. This is a growing market in Ireland, with adventure sports taking off. I would also hope to sell advertising to service providers in this industry also. This is a part time project for me as I work full time, I am also not an IT person. I have taken this as far as I have given the time I have, but I believe the Idea has merit so I will push on for a while. Other areas that will need attention are marketing, social media etc. For now I would like a cost to carry out the tasks 1) changing the web domain name to another I own [login to view URL] and 2) Creating an alternative home page to the blog one that exists and a 3rd, 3) Identify any further opportunities for improvement given the overall objectives. I can only allocate a small fee towards this work package, and will have to spread out further work from month to month. As an incentive, if this project proves to be a runner/success (the definition of success to be be decided at a later date, but will be based on income generation), there may be an opportunity for some shared ownership. I look forward to hearing from you, and if you require any more information, please let me know. Regards Peter
