Singer for Wedding in Birmingham

Hello, it is my wedding next year on Saturday 4th of July. The wedding venue is just outside of Birmingham. For the reception I would like live music and not a DJ. Happy for either a band or a solo singer, depending on the price. There will be around 300 people. I would like a set of around 4 hours (7 til 11). Music to be a good mixture of popular songs both present and past. I would like to see song lists and prices from acts near Birmingham. Please give prices with and without a sound system. I would like to know what other costs may be involved and how it all works.
